If a Fundamental Change occurs, then each Holder shall have the right, at such Holder’s option, to require the Company to purchase for cash all of such Holder’s Notes, or any portion of such Holder’s Notes that is equal to $1,000, or an integral multiple of $1,000 in excess thereof, on a date (the “Fundamental Change Purchase Date”) specified by the Company that is not less than 20 or more than 35 Business Days after the occurrence of such Fundamental Change, at a purchase price equal to 100% of the principal amount of the Notes to be purchased, plus accrued and unpaid interest to but excluding the Fundamental Change Purchase Date (the “Fundamental Change Purchase Price”); provided, however, that if the Fundamental Change Purchase Date is after a Regular Record Date and on or prior to the Interest Payment Date to which it relates, the Company shall instead pay interest accrued to the Interest Payment Date to the Holder of record of the Note as of the preceding Regular Record Date and the Fundamental Change Purchase Price shall then be equal to 100% of the principal amount of the Note subject to purchase and shall not include any accrued and unpaid interest. Notwithstanding the foregoing, there shall be no purchase of any Notes pursuant to this Section 3.01 if the principal amount of the Notes has

been accelerated, and such acceleration has not been rescinded, on or prior to the Fundamental Change Purchase Date (except in the case of an acceleration resulting from a Default by the Company in the payment of the Fundamental Change Purchase Price with respect to such Notes). In the event the principal amount of the Notes is accelerated following delivery of a Fundamental Change Company Notice (except in the case of an acceleration resulting from a Default by the Company in the payment of the Fundamental Change Purchase Price with respect to such Notes), the Trustee shall promptly (i) return to the respective Holders thereof any Physical Notes tendered to it or (ii) effect appropriate book-entry transfers to the respective beneficial holders thereof any beneficial interests in a Global Note tendered to it in compliance with the Applicable Procedures, in which case, upon such return or transfer, as the case may be, the Fundamental Change Purchase Notice with respect thereto shall be deemed to have been withdrawn.

Section 3.02 Fundamental Change Company Notice.

(a) General. On or before the 10th Business Day after the occurrence of a Fundamental Change, the Company shall mail to all Holders of the Notes, the Trustee and the Paying Agent (in the case of any Paying Agent other than the Trustee) a written notice (the “Fundamental Change Company Notice”) of the occurrence of such Fundamental Change and of the purchase right at the option of the Holders arising as a result thereof. Such notice shall be sent to the Holders in accordance with Section 12.08(c) (with a copy to the Trustee). In addition to providing such Fundamental Change Company Notice, on or before the 10th Business Day after the occurrence of such Fundamental Change, the Company shall issue a press release announcing the occurrence of such Fundamental Change and make the press release available on the Company’s website. Each Fundamental Change Company Notice shall specify:

(i) the events causing the Fundamental Change;

(ii) the Effective Date of the Fundamental Change, and whether the Fundamental Change is a Make-Whole Adjustment Event;

(iii) the last date on which a Holder of Notes may exercise the purchase right pursuant to Section 3.01;

(iv) the Fundamental Change Purchase Price;

(v) the Fundamental Change Purchase Date;

(vi) the name and address of the Paying Agent and the Conversion Agent, if applicable;

(vii) the applicable Conversion Rate and any adjustments to the applicable Conversion Rate resulting from the Fundamental Change, and the procedures required for exercise of a Holder’s right to convert its Notes as described in Section 4.02;

(viii) if applicable, that the Notes with respect to which a Fundamental Change Purchase Notice has been delivered by a Holder may be converted only if the Holder withdraws the Fundamental Change Purchase Notice in accordance with Section 3.05;

(ix) the procedures required for exercise of the purchase option upon the Fundamental Change, including that the Holder must exercise the purchase option prior to the Fundamental Change Expiration Time; and

(x) that the Holder shall have the right to withdraw any Notes surrendered for purchase prior to the Fundamental Change Expiration Time and the procedures required for withdrawal of any such exercise as described in 3.05;

(b) No failure of the Company to give the foregoing notices and no defect therein shall limit the Holders’ repurchase rights or affect the validity of the proceedings for the repurchase of the Notes pursuant to Section 3.01.

(c) At the Company’s written request, the Trustee shall give the Fundamental Change Company Notice in the Company’s name and at the Company’s expense; provided, however, that, in all cases, the Fundamental Change Company Notice shall be prepared by the Company; provided, further that the Company shall have delivered to the Trustee, at least five Business Days before the Fundamental Change Company Notice is required to be given to the Holders (or such shorter period agreed to by the Trustee), an Officers’ Certificate requesting that the Trustee give such notice and attaching the form of Fundamental Change Company Notice and including the information required by Section 3.02(a). Neither the Trustee nor the Paying Agent shall be responsible for determining if a Fundamental Change has occurred or for delivering a Fundamental Change Company Notice to Holders or for the content of any Fundamental Change Company Notice.

Section 3.03 Repurchase Procedures.

(a) Purchases of Notes under Section 3.01 shall be made, at the option of the Holder thereof, upon:

(i) if the Notes to be purchased are Physical Notes, delivery to the Trustee and the Paying Agent by the Holder of a duly completed notice in the Form of Fundamental Change Purchase Notice (the “Fundamental Change Purchase Notice”) together with the Physical Notes duly endorsed for transfer, at any time prior to the Close of Business on the Business Day immediately preceding the Fundamental Change Purchase Date, (the “Fundamental Change Expiration Time”); and

(ii) if the Notes to be purchased are Global Notes, delivery to the Trustee and the Paying Agent of the beneficial interest in such Global Notes, by

book-entry transfer, in compliance with the Applicable Procedures and the satisfaction of any other requirements of the Depositary in connection with tendering beneficial interests in a Global Note for purchase by the Fundamental Change Expiration Time.

The Fundamental Change Purchase Notice in respect of any Notes to be purchased shall state:

(i) if certificated, the certificate numbers of such Holder’s Notes to be purchased;

(ii) the portion of the principal amount of such Notes to be purchased, equal to $1,000 or an integral multiple of $1,000 in excess thereof; and

(iii) that such Notes are to be purchased by the Company pursuant to the applicable provisions of the Notes and this Supplemental Indenture.

(b) Notice to Company. The Paying Agent shall promptly notify the Company of the receipt by it of any Fundamental Change Purchase Notice or written notice of withdrawal thereof.

Section 3.04 Effect of Fundamental Change Purchase Notice. Upon receipt by the Paying Agent of Physical Notes and a Fundamental Change Purchase Notice or beneficial interests in a Global Note by book-entry transfer as specified in Section 3.03, the Holder of the tendered Note shall (unless such Fundamental Change Purchase Notice is withdrawn in accordance with Section 3.05) thereafter be entitled to receive solely the Fundamental Change Purchase Price, in cash with respect to such Note (and any previously accrued and unpaid interest on such Note, if applicable). Provided that a Holder has tendered its Notes by book-entry transfer or delivery to the Trustee, such Fundamental Change Purchase Price shall be paid to such Holder, provided that the conditions in this Article 3 have been satisfied (including, without limitation, the proper delivery or book-entry transfer of such Note as required under Section 3.03(a)) and subject to the Paying Agent holding money sufficient to pay the Fundamental Change Purchase Price, on the applicable Fundamental Change Purchase Date or, if later, the time of delivery or book-entry transfer of such Note to the Paying Agent by the Holder thereof in the manner required by Section 3.01.

Section 3.05 Withdrawal of Fundamental Change Purchase Notice. A Fundamental Change Purchase Notice may be withdrawn (in whole or in part) by means of a written notice of withdrawal delivered to the Paying Agent in accordance with the Fundamental Change Company Notice, as applicable, at any time prior to the Fundamental Change Expiration Time, as applicable, specifying:

(a) the principal amount of the Notes with respect to which such notice of withdrawal is being submitted;

(b) if certificated, the certificate numbers of the withdrawn Notes; and

(c) the principal amount, if any, of each Note that remains subject to the Fundamental Change Purchase Notice, equal to $1,000 or an integral multiple of $1,000 in excess thereof;

provided, however, that if the Notes are Global Notes, the notice must comply with the Applicable Procedures.

The Paying Agent shall promptly return to the respective Holders thereof any Physical Notes with respect to which a Fundamental Change Purchase Notice has been withdrawn in compliance with the provisions of this Section 3.05.

Section 3.06 Deposit of Fundamental Change Purchase Price. Prior to 11:00 a.m., New York City time, on the Fundamental Change Purchase Date, the Company shall deposit with the Paying Agent (or, if the Company or a Subsidiary or an Affiliate of either of them is acting as the Paying Agent, shall segregate and hold in trust as provided herein) an amount of money (in immediately available funds if deposited on such Business Day) sufficient to pay the Fundamental Change Purchase Price of all the Notes or portions thereof that are to be purchased as of the Fundamental Change Purchase Date. If the Paying Agent holds money sufficient to pay the Fundamental Change Purchase Price of the tendered Notes on the Fundamental Change Purchase Date, then, with respect to the Notes that have been properly surrendered for the purchase and not validly withdrawn: (a) such tendered Notes shall cease to be Outstanding and interest shall cease to accrue thereon (whether or not book-entry transfer of the Notes is made or whether or not the Note is delivered to the Paying Agent) and (b) all other rights of the Holders of such tendered Notes shall terminate (other than the right to receive the Fundamental Change Purchase Price and, if the Fundamental Change Purchase Date is after a Regular Record Date and on or prior to the related Interest Payment Date, the right of the Holder of record on such Regular Record Date to receive any interest payment pursuant to Section 3.01).

Section 3.07 Notes Purchased in Whole or in Part. Any Note that is to be purchased pursuant to this Article 3, whether in whole or in part, shall be surrendered at the office of the Paying Agent (with due endorsement by, or a written instrument of transfer in form satisfactory to the Company duly executed by, the Holder thereof or such Holder’s attorney duly authorized in writing) and, to the extent that only a part of the Note so surrendered is to be purchased, the Company shall execute and, upon receipt of a Company Order, the Trustee shall authenticate and deliver to the Holder of such Note, without service charge, a new Note or Notes, of any authorized denomination as requested by such Holder in aggregate principal amount equal to, and in exchange for, the portion of the principal amount of the Note so surrendered that is not purchased.

Section 3.08 Covenant To Comply with Applicable Laws upon Purchase of Notes. In connection with any purchase of Notes under Section 3.01, the Company shall, in each case if required by law, (i) comply with the provisions of Rule 13e-4, Rule 14e-1 and any other tender offer rules under the Exchange Act to the extent any such rules are applicable, (ii) file a Schedule TO or any successor or similar schedule, if required, under the Exchange Act and (iii) otherwise comply with all U.S. federal or state securities laws applicable to the Company in connection

with such purchase offer, in each case, so as to permit the rights and obligations under this Article 3 to be exercised in the time and in the manner specified under this Article 3.

Section 3.09 Repayment to the Company. To the extent that the aggregate amount of money deposited by the Company pursuant to Section 3.06 exceeds the aggregate Fundamental Change Purchase Price of the Notes or portions thereof that the Company is obligated to purchase as of the Fundamental Change Purchase Date, then, following the Fundamental Change Purchase Date, the Paying Agent shall, upon demand of the Company, promptly return any such excess to the Company.

ARTICLE 4.
CONVERSION

Section 4.01 Right To Convert. (a) Subject to and upon compliance with the provisions of this Supplemental Indenture, each Holder shall have the right, at such Holder’s option, to convert all or any portion of its Notes at an initial Conversion Rate of 28.4627 shares of Common Stock per $1,000 aggregate principal amount of Notes (equivalent to an initial Conversion Price of approximately $35.13 per share of Common Stock) into the Settlement Amount determined in accordance with Section 4.03(a)(ii), at any time until the Close of Business on the Business Day immediately preceding the Free Convertibility Date, (x) only upon satisfaction of one or more of the conditions described in Section 4.01(b), and (y) on or after the Free Convertibility Date, at any time until the Close of Business on the second Scheduled Trading Day immediately preceding the Maturity Date regardless of whether the conditions described in Section 4.01(b) are satisfied.

(b) (i) A Holder may surrender all or any portion of its Notes for conversion during any calendar quarter (and only during such calendar quarter) commencing after the calendar quarter ending December 31, 2014 if the Closing Sale Price of the Common Stock for at least 20 Trading Days (whether or not consecutive) during the period of 30 consecutive Trading Days ending on the last Trading Day of the calendar quarter immediately preceding the calendar quarter in which the conversion occurs, is more than 130% of the applicable Conversion Price in effect on each applicable Trading Day.

(ii) If, prior to the Close of Business on the Business Day immediately preceding the Free Convertibility Date, the Trading Price per $1,000 principal amount of Notes on each Trading Day during any ten consecutive Trading Day period (the “Measurement Period”) is less than 98% of the product of (x) the Closing Sale Price of the Common Stock on such date and (y) the applicable Conversion Rate on such Trading Day, a Holder may surrender Notes for conversion at any time during the five consecutive Business Days following such Measurement Period. The Bid Solicitation Agent shall, on the Company’s behalf, determine if the Notes are convertible and shall notify the Company and the Trustee in writing accordingly. However, the Bid Solicitation Agent (if other than the Company) shall have no obligation to solicit market bid quotations for the Company to determine the Trading Price of the Notes unless the Company has requested such solicitation in writing; and the

Company shall have no obligation to make such request (or, if the Company is the Bid Solicitation Agent, to determine the Trading Price of the Notes) unless a Holder of a Note provides the Company and the Trustee with reasonable evidence that the Trading Price per $1,000 principal amount of Notes on any Trading Day would be less than 98% of the product of (x) the Closing Sale Price of the Common Stock on such Trading Day and (y) the Conversion Rate in effect on such Trading Day. At such time, the Company shall instruct the Bid Solicitation Agent (if other than the Company) to determine, or, if the Company is acting as the Bid Solicitation Agent, the Company shall determine, the Trading Price of the Notes beginning on the next Trading Day and on each of the next nine Trading Days. If, at any time after the condition to conversion set forth in this Section 4.01(b)(ii) has been met, the Trading Price for the Notes on any Trading Day is greater than or equal to 98% of the product of (x) the Closing Sale Price of the Common Stock on such Trading Day and (y) the Conversion Rate in effect on such Trading Day, the Bid Solicitation Agent shall, on the Company’s behalf so notify the Holders and the Trustee.

(iii) If the Company elects to issue or distribute, as the case may be, to all or substantially all holders of the Common Stock (x) any rights, options or warrants entitling them to subscribe for or purchase, for a period expiring within 45 calendar days after the declaration date for such issuance, shares of the Common Stock, at a price per share that is less than the average of the Closing Sale Prices of the Common Stock for the ten consecutive Trading Days immediately preceding the declaration date for such issuance; or (y) cash, debt securities (or other evidence of indebtedness) or other assets or securities (including for the avoidance of doubt, any rights, options or warrants that are not described in the proceeding clause (x), but excluding dividends or distributions in respect of which an adjustment to the Conversion Rate is made pursuant to Section 4.04(a)), which distribution has a per share value exceeding 10% of the Closing Sale Price of the Common Stock as of the Trading Day immediately preceding the declaration date for such distribution, then, in either case, the Company must deliver notice of such distribution, and of the Ex-Dividend Date for such distribution, to the Holders at least 50 Scheduled Trading Days prior to the Ex-Dividend Date for such distribution. After the Company has delivered such notice, Holders may surrender their Notes for conversion at any time until the earlier of (a) the Close of Business on the Business Day immediately preceding such Ex-Dividend Date for such distribution and (b) the Company’s announcement that such issuance or distribution shall not take place; provided, however, that a Holder may not exercise this right to convert if the Holder may participate in the distribution without conversion of the Notes as if it held a number of shares of Common Stock equal to the Conversion Rate.

(iv) If a transaction or event that constitutes a Fundamental Change or a Make-Whole Adjustment Event occurs, a holder may surrender Notes for conversion at any time from and after the date that is 50 Scheduled Trading Days prior to the anticipated effective date of the transaction or event until the Close of

Business on (x) if such transaction or event is a Fundamental Change, the Business Day immediately preceding the related Fundamental Change Purchase Date, or (y) otherwise, the 40th Scheduled Trading Day immediately following the effective date for such transaction or event. To the extent practicable, the Company shall give notice to Holders of the anticipated effective date for such transaction or event not less than 50 Scheduled Trading Days prior to the anticipated effective date or, if the Company does not have knowledge of such transaction or event at least 50 Scheduled Trading Days prior to the anticipated effective date, within two Business Days of the date upon which the Company receives notice, or otherwise becomes aware of, such transaction or event (but in no event later than the actual effective date of such transaction or event).

(v) Holders shall have the right to surrender Notes for conversion if the Company is a party to a consolidation, merger or binding share exchange or a sale, assignment, conveyance, transfer, lease or other disposition of all or substantially all of the Company’s property and assets that does not also constitute a Fundamental Change or a Make-Whole Adjustment Event, in each case pursuant to which the Common Stock would be converted into cash, securities or other property. In such event, Holders shall have the right to surrender Notes for conversion at any time from and including the 50th Scheduled Trading Day prior to the anticipated effective date of such transaction to, and including, the 40th Scheduled Trading Day following the effective date of such transaction. The Company shall notify the Holders at least 50 Scheduled Trading Days prior to the anticipated effective date of such transactions or, if such effective date is anticipated to occur in less than 50 Scheduled Trading Days after the date upon which the Company receives notice, or otherwise became aware, of such transaction or event, within two Business Days of the date upon which the Company receives notice, or otherwise becomes aware, of such transaction or event (but in no event later than the actual effective date of such transaction or event).

Section 4.02 Conversion Procedures.

(a) Each Note shall be convertible at the office of the Conversion Agent and, if applicable, in accordance with the Applicable Procedures.

(b) To exercise the conversion privilege with respect to a beneficial interest in a Global Note, the Holder must comply with the Applicable Procedures for converting a beneficial interest in a Global Note and any taxes or duties if required pursuant to Section 4.02(g), and the Conversion Agent must be informed of the conversion in accordance with the customary practice of the Depositary.

To exercise the conversion privilege with respect to any Physical Notes, the Holder of such Physical Notes shall:

(i) complete and manually sign a conversion notice in the form set forth in the Form of Notice of Conversion (the “Conversion Notice”) or a facsimile of the Conversion Notice;

(ii) deliver the Conversion Notice, which is irrevocable, and the Physical Note to the Conversion Agent;

(iii) if required, furnish appropriate endorsements and transfer documents;

(iv) if required, pay all transfer or similar taxes as set forth in Section 4.02(g); and

(v) if required, make any payment required under Section 4.02(f).

If, upon conversion of a Note, any shares of Common Stock are to be issued to a Person other than the Holder of such Note, the related Conversion Notice shall include such other Person’s name and address.

If a Note has been submitted for repurchase pursuant to a Fundamental Change Purchase Notice, such Note may not be converted except to the extent the Fundamental Change Purchase Notice with respect to such Note has been withdrawn by the Holder in accordance with Section 3.05 and such Note is no longer submitted for repurchase pursuant to a Fundamental Change Purchase Notice.

For any Note, the date on which the Holder of such Note satisfies all of the applicable requirements set forth above with respect to such Note shall be the “Conversion Date” with respect to such Note. The Company shall determine the Conversion Date for each such Note in accordance with the requirements set forth herein.

Each conversion shall be deemed to have been effected as to any such Notes (or portion thereof) surrendered for conversion at the Close of Business on the applicable Conversion Date; provided, however, that except to the extent required by Section 4.04, the person in whose name any shares of Common Stock shall be issuable upon conversion, if any, shall be treated as a stockholder of record of such shares as of the Close of Business on the Conversion Date (in the case of Physical Settlement) or on the last VWAP Trading Day of the relevant Conversion Period (in the case of any other Settlement Method). For the avoidance of doubt, until a Holder is deemed to become the holder of record of shares of Common Stock issuable upon conversion of such Holder’s Notes as contemplated in the immediately preceding sentence, such Holder shall not have any rights as a holder of the Common Stock with respect to the shares of Common Stock issuable upon conversion of such Notes. At the Close of Business on the Conversion Date for a Note, the converting Holder shall no longer be the Holder of such Note.

(c) Endorsement. Any Notes surrendered for conversion shall, unless shares of Common Stock issuable on conversion are to be issued in the same name as the registration of such Notes, be duly endorsed by, or be accompanied by instruments of

transfer in form satisfactory to the Company duly executed by, the Holder or its duly authorized attorney.

(d) Physical Notes. If any Physical Notes in a denomination greater than $1,000 shall be surrendered for partial conversion, the Company shall execute and the Trustee shall upon receipt of a Company Order authenticate and deliver to the Holder of the Physical Notes so surrendered, without charge, new Physical Notes in authorized denominations in an aggregate principal amount equal to the unconverted portion of the surrendered Physical Notes.

(e) Global Notes. Upon the conversion of a beneficial interest in Global Notes, the Conversion Agent shall make a notation in its records as to the reduction in the principal amount represented thereby. The Company shall notify the Trustee in writing of any conversions of Notes effected through any Conversion Agent other than the Trustee.

(f) Interest Due Upon Conversion. If a Holder converts a Note after the Close of Business on a Regular Record Date but prior to the Open of Business on the Interest Payment Date corresponding to such Regular Record Date, in addition to tendering such Note to the Conversion Agent in accordance with Section 4.02(b) such Holder must deliver directly to the Company an amount of cash equal to the amount of interest that shall payable on such Note on the corresponding Interest Payment Date; provided, however, that a Holder need not make such payment (1) if the Company has specified a Fundamental Change Purchase Date that is after a Regular Record Date and on or prior to the corresponding Interest Payment Date; (2) if the Conversion Date follows the Regular Record Date immediately preceding the Maturity Date; or (3) to the extent of any overdue interest, if any overdue interest exists at the time of conversion with respect to such Note.

(g) Taxes Due upon Conversion. If a Holder converts a Note and the Company elects to deliver shares of Common Stock, the Company shall pay any documentary, stamp or similar issue or transfer tax due on the issue of any shares of the Common Stock upon the conversion, unless the tax is due because the Holder requests that any shares be issued in a name other than the Holder’s name or delivered to a person other than the Holder, in which case the Holder shall pay that tax.

Section 4.03 Settlement Upon Conversion.

(a) Settlement. Subject to this Section 4.03 and Sections 4.05 and 4.06, upon conversion of a Note, the Company shall pay or deliver, as the case may be, to Holders, in full satisfaction of, its conversion obligation under Section 4.01, in respect of each $1,000 principal amount of Notes being converted, a Settlement Amount consisting of, at the election of the Company, solely cash (“Cash Settlement”), shares of Common Stock (together with cash in lieu of any fractional share of Common Stock pursuant to Section 4.03(b)) (“Physical Settlement”) or through payment and delivery, as the case

may be, of a combination of cash and shares of Common Stock with a particular Specified Dollar Amount (“Combination Settlement”).

(i) Settlement Election. All conversions occurring on or after the Final Settlement Method Election Date shall be settled using the same Settlement Method. Prior to the Final Settlement Method Election Date the Company shall use the same Settlement Method for all conversions occurring on the same Conversion Date, but the Company shall not have any obligation to use the same Settlement Method with respect to conversions that occur on different Conversion Dates. If the Company elects a Settlement Method (a “Settlement Election”) and a Specified Dollar Amount, if applicable (a “Specified Dollar Amount Election”) on or prior to the Final Settlement Method Election Date, the Company shall provide to the Holders so converting through the Trustee a written notice of such Settlement Method (each such notice, a “Settlement Election Notice”) or such Specified Dollar Amount (each such notice, a “Specified Dollar Amount Election Notice”), no later than the Close of Business on the second Trading Day immediately following the related Conversion Date unless the Company has previously made an irrevocable election pursuant to the immediately following paragraph. If the Company does not timely elect a Settlement Method, the Company shall no longer have the right to elect Cash Settlement or Physical Settlement, and the Company shall be deemed to have elected Combination Settlement in respect of its conversion obligation, and the Specified Dollar Amount per $1,000 principal amount of Notes shall be deemed to be $1,000. If the Company elects Combination Settlement but does not timely notify the Holders of the Specified Dollar Amount per $1,000 principal amount of Notes, such Specified Dollar Amount shall be deemed to be $1,000.

In addition, the Company may, prior to the Final Settlement Method Election Date, at its option, irrevocably elect Combination Settlement with a particular Specified Dollar Amount for all conversions subsequent to the Company’s such irrevocable notice to Holders by written notice of such election to the Holders, the Trustee and the Conversion Agent.

(ii) Settlement Amount. The cash, shares of Common Stock or combination of cash and shares of Common Stock in respect of any conversion of Notes (the “Settlement Amount”) shall be computed as follows:

(A) if the Company elects to satisfy its conversion obligation through Physical Settlement, the Company shall deliver to the converting Holder, in respect of each $1,000 principal amount of its Notes being converted, a number of shares of Common Stock equal to the Conversion Rate in effect on the Conversion Date for such conversion, together with cash in lieu of any fractional shares of Common Stock pursuant to Section 4.03(b);

(B) if the Company elects to satisfy its conversion obligation through Cash Settlement, the Company shall pay to the converting Holder, in

respect of each $1,000 principal amount of its Notes being converted, cash in an amount equal to the sum of the Daily Conversion Values for each of the 40 consecutive VWAP Trading Days during the related Conversion Period; and

(C) if the Company elects (or is deemed to have elected) to satisfy its conversion obligation through Combination Settlement, the Company shall pay or deliver, as the case may be, to the converting Holder, in respect of each $1,000 principal amount of its Notes being converted, an amount of cash and number of shares of Common Stock, if any, equal to the sum of the Daily Settlement Amounts for each of the 40 consecutive VWAP Trading Days during the related Conversion Period.

(iii) Delivery Obligation. The Company shall pay or deliver, as the case may be, the Settlement Amount due in respect of its conversion obligation under this Section 4.03, (x) on the third Business Day immediately following the relevant Conversion Date, if the Company elects Physical Settlement, unless such Conversion Date occurs following the Regular Record Date immediately preceding the Maturity Date, in which case the Company shall make such delivery (and payment, if applicable) on the Maturity Date or (y) on the third Business Day immediately following the last VWAP Trading Day of the related Conversion Period, in any other case; provided, however, that, in the case of clause (x) or (y) above, if prior to the Conversion Date for any converted Notes, the Common Stock has been replaced by Reference Property consisting solely of cash, the Company shall pay the consideration due in respect of such conversion on the tenth Business Day immediately following the related Conversion Date, and, notwithstanding the foregoing in this Section 4.03, no Conversion Period shall apply to those conversions. For the avoidance of doubt, in the case of Cash Settlement or Combination Settlement, if a VWAP Market Disruption Event occurs on a Scheduled Trading Day during the Conversion Period, or if such Scheduled Trading day is not a VWAP Trading Day for any other reason, then the Daily Conversion Value or Daily Settlement Amount, as applicable, will be determined on the next following VWAP Trading Day, and delivery of the Settlement Amount will be delayed accordingly. No interest will accrue on account of such delay.

(b) Fractional Shares. Notwithstanding the foregoing, the Company shall not issue fractional shares of Common Stock as part of the Settlement Amount due with respect to any converted Note. Instead, if any Settlement Amount includes a fraction of a share of the Common Stock, the Company shall, in lieu of delivering such fraction of a share of Common Stock, pay an amount of cash equal to the product of such fraction of a share and (i) in a Physical Settlement, the Daily VWAP on the relevant Conversion Date, or if such Conversion Date is not a VWAP Trading Day, the immediately preceding VWAP Trading Day or (ii) in the case of any other Settlement Method, the Daily VWAP on the last VWAP Trading Day of the relevant Conversion Period (subject to Section 4.03(c) immediately below).

(c) Conversion of Multiple Notes by a Single Holder. If a Holder surrenders more than one Note for conversion on a single Conversion Date, the Company will calculate the number of shares of Common Stock due with respect to such Notes as if such Holder had surrendered for conversion one Note having an aggregate principal amount equal to the sum of the principal amounts of each of the Notes surrendered for conversion by such Holder on such Conversion Date.

(d) Settlement of Accrued Interest and Deemed Payment of Principal. If a Holder converts a Note, the Company shall not adjust the Conversion Rate to account for any accrued and unpaid interest on such Note, and the Company’s delivery or payment, as the case may be, of cash, shares of Common Stock or a combination of cash and shares of Common Stock into which a Note is convertible shall be deemed to satisfy and discharge in full the Company’s obligation to pay the principal of, and accrued and unpaid interest, if any, on, such Note to, but excluding, the Conversion Date; provided, however, that subject to Section 4.02(f), if a Holder converts a Note after the Close of Business on a Regular Record Date and prior to the Open of Business on the corresponding Interest Payment Date, the Company shall still be obligated to pay the interest due on such Interest Payment Date to the Holder of such Note on such Regular Record Date.

As a result, except as otherwise provided in the proviso to the immediately preceding sentence, any accrued and unpaid interest with respect to a converted Note shall be deemed to be paid in full rather than cancelled, extinguished or forfeited. In addition, if the Settlement Amount for any Note includes both cash and shares of Common Stock, accrued and unpaid interest shall be deemed to be paid first out of the amount of cash delivered upon such conversion.

(e) Notices. Whenever a Conversion Date occurs with respect to a Note, the Conversion Agent shall, as promptly as possible, and in no event later than the Business Day immediately following such Conversion Date, deliver to the Company and the Trustee, if it is not then the Conversion Agent, written notice that a Conversion Date has occurred, which notice shall state such Conversion Date, the principal amount of Notes converted on such Conversion Date and the names of the Holders that converted Notes on such date. The Company shall promptly notify the Trustee and Conversion Agent in writing of any payments made pursuant to Sections 4.02(f) or 4.02(g), as applicable. The Company will notify the Trustee and the Conversion Agent in writing upon the occurrence of the Conversion Date for each Note tendered for conversion.

On the first Business Day immediately following the last VWAP Trading Day of the Conversion Period applicable to any Note surrendered for conversion in a Cash Settlement or a Combination Settlement, the Company shall deliver a written notice to the Conversion Agent and the Trustee (if not also the Conversion Agent) stating the amount of cash and the number of shares of Common Stock, if any, that the Company is obligated to pay or deliver, as the case may be, to satisfy its conversion obligation with respect to each Note converted on such Conversion Date.

Section 4.04 Adjustment of Conversion Rate. The Conversion Rate shall be adjusted as described in this Section 4.04, except that the Company shall not make any adjustment to the Conversion Rate if Holders are entitled to participate (other than in the case of a share split or share combination), at the same time and upon the same terms as holders of the Common Stock and as a result of holding the Notes, in any of the transactions described below without having to convert their Notes, as if they held a number of shares of Common Stock equal to the applicable Conversion Rate, multiplied by the principal amount (expressed in thousands) of Notes held by such Holder.

(a) If the Company exclusively issues shares of Common Stock as a dividend or distribution on all or substantially all shares of the Common Stock, or if the Company effects a share split or share combination, the Conversion Rate shall be adjusted based on the following formula:

CR1 = CR0 x	OS1
	OS0

where,

CR0 =	the Conversion Rate in effect immediately prior to the Open of Business on the Ex-Dividend Date of such dividend or distribution, or immediately prior to the Open of Business on the Effective Date of such share split or combination, as applicable;

CR1 =	the Conversion Rate in effect immediately after the Open of Business on such Ex-Dividend Date or immediately after the Open of Business on such Effective Date, as applicable;

OS0 =	the number of shares of Common Stock outstanding immediately prior to the Open of Business on such Ex-Dividend Date or immediately prior to the Open of Business on such Effective Date, as applicable; and

OS1 =	the number of shares of Common Stock outstanding immediately after giving effect to such dividend or distribution, or immediately after the Effective Date of such share split or share combination, as applicable.

Any adjustment made under this Section 4.04(a) shall become effective immediately after the Open of Business on the Ex-Dividend Date for such dividend or distribution, or immediately after the Open of Business on the Effective Date for such share split or share combination. If any dividend or distribution of the type described in this Section 4.04(a) is declared but not so paid or made, the Conversion Rate shall be immediately readjusted, effective as of the date the Board of Directors determines not to pay such dividend or distribution or to effect such share split or share combination, to the Conversion Rate that would then be in effect if such dividend or distribution had not been declared or such share split or share combination had not been announced.

(b) If an Ex-Dividend Date occurs for a distribution to all or substantially all holders of the Common Stock of any rights, options or warrants entitling them, for a period of not more than 45 calendar days from the announcement date of such distribution, to subscribe for or purchase shares of the Common Stock, at a price per share less than the average of the Closing Sale Prices of the Common Stock for the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of such distribution, the Conversion Rate shall be increased based on the following formula:

CR1 = CR0 x	OS0 + X
CR1 = CR0 x	OS0 + Y

where,

CR0 =	the Conversion Rate in effect immediately prior to the Open of Business on the Ex-Dividend Date for such distribution;

CR1 =	the Conversion Rate in effect immediately after the Open of Business on such Ex-Dividend Date;

OS0 =	the number of shares of Common Stock outstanding immediately prior to the Open of Business on such Ex-Dividend Date;

X =	the total number of shares of Common Stock issuable pursuant to such rights, options or warrants; and

Y =	the number of shares of Common Stock equal to the aggregate price payable to exercise such rights, options or warrants divided by the average of the Closing Sale Prices of the Common Stock over the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of the distribution of such rights, options or warrants.

Any increase made under this Section 4.04(b) shall be made successively whenever any such rights, options or warrants are issued and shall become effective immediately after the Open of Business on the Ex-Dividend Date for such distribution. To the extent that such rights, options or warrants are not exercised prior to their expiration or shares of Common Stock are not delivered upon the expiration of such rights, options or warrants, the Conversion Rate shall be readjusted to the Conversion Rate that would then be in effect had the increase with respect to the issuance of such rights, options or warrants been made on the basis of delivery of only the number of shares of Common Stock actually delivered. If such rights, options or warrants are not so distributed, or if such rights, options or warrants are not exercised prior to their expiration, the Conversion Rate shall be decreased to be the Conversion Rate that would then be in effect if the Ex-Dividend Date for such distribution had not occurred.

For purposes of this Section 4.04(b) and Section 4.01(b)(iii)(x), in determining whether any rights, options or warrants entitle the holders of the Common Stock to subscribe for or purchase shares of the Common Stock at a price per share less than the average of the Closing Sale Prices of the Common Stock for the 10 consecutive Trading Day period ending on the Trading Day immediately preceding the date of announcement for such distribution, there shall be taken into account any consideration received by the Company for such rights, options or warrants and any amount payable on exercise thereof, with the value of such consideration, if other than cash, to be determined in good faith by the Board of Directors.

(c) If an Ex-Dividend Date occurs for a Company distribution of shares of its Capital Stock, evidences of its indebtedness, other assets or property of the Company or rights, options or warrants to acquire its Capital Stock or other securities, to all or substantially all holders of the Common Stock (any of such shares of Capital Stock, evidences of indebtedness, other assets or property or rights, options or warrants to acquire Capital Stock or other securities of the Company, the “Distributed Property”), excluding:

(i) dividends or distributions and rights, options or warrants as to which an adjustment was effected pursuant to Section 4.04(a) or Section 4.04(b);

(ii) dividends or distributions paid exclusively in cash as to which an adjustment was effected pursuant to Section 4.04(d); and

(iii) Spin-Offs as to which the provisions set forth below in this Section 4.04(c) shall apply,

then the Conversion Rate shall be increased based on the following formula:

CR1 = CR0 x	SP0
CR1 = CR0 x	SP0 - FMV

where,

CR0 =	the Conversion Rate in effect immediately prior to the Open of Business on the Ex-Dividend Date for such distribution;

CR1 =	the Conversion Rate in effect immediately after the Open of Business on such Ex-Dividend Date;

SP0 =	the average of the Closing Sale Prices of the Common Stock over the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Ex-Dividend Date for such distribution; and

FMV =

the fair market value (as determined in good faith by the Board of Directors) of Distributed Property with respect to each outstanding share of the Common Stock as of the Open of Business on the Ex-Dividend Date for such distribution.

If “FMV” (as defined above) is equal to or greater than the “SP0” (as defined above), in lieu of the foregoing increase, each Holder of Notes shall receive, in respect of each $1,000 principal amount of Notes it holds, at the same time and upon the same terms as holders of the Common Stock, without having to convert its Notes, the amount and kind of Distributed Property that such Holder would have received as if such Holder owned a number of shares of Common Stock equal to the Conversion Rate in effect immediately prior to the Record Date for the distribution.

Any increase made pursuant to the formula above shall become effective immediately after the Open of Business on the Ex-Dividend Date for such distribution. If such distribution is not so paid or made, the Conversion Rate shall be decreased to be the Conversion Rate that would then be in effect if such dividend or distribution had not been declared.

With respect to an adjustment pursuant to this Section 4.04(c), where there has been an Ex-Dividend Date for a payment of a dividend or other distribution on the Common Stock of shares of Capital Stock of any class or series, or similar equity interest, of or relating to any Subsidiaries of the Company or business units of the Company, and such Capital Stock or similar equity interest is listed or quoted (or shall be listed or quoted upon the consummation of the distribution) on a U.S. national securities exchange (a “Spin-Off”), the Conversion Rate shall be increased based on the following formula:

CR1 = CR0 x	FMV0 + MP0
CR1 = CR0 x	MP0

where,

CR0 =	the Conversion Rate in effect immediately prior to the Open of Business on the Ex-Dividend Date for such Spin-Off;

CR1 =	the Conversion Rate in effect immediately after the Open of Business on the Ex-Dividend Date for such Spin-Off;

FMV0 =	the average of the Closing Sale Prices of the Capital Stock or similar equity interest distributed to holders of Common Stock applicable to one share of Common Stock over the first 10 consecutive Trading Day period commencing on, and including, the Ex-Dividend date for the Spin-Off (the “Valuation Period”); and

MP0 =	the average of the Closing Sale Prices of Common Stock over the Valuation Period.

The adjustment to the Conversion Rate under the preceding paragraph shall be determined on the last Trading Day of the Valuation Period but shall be given effect immediately after the Open of Business on the Ex-Dividend Date for the Spin-Off. If the Ex-Dividend Date for the Spin-Off is less than 10 consecutive Trading Days prior to, and including, the end of the Conversion Period in respect of any conversion, references within this Section 4.04(c) to 10 consecutive Trading Days shall be deemed to be replaced, solely in respect of that conversion, with such lesser number of Trading Days as have elapsed from, and including, the Ex-Dividend Date for the Spin-Off to, and including, the last VWAP Trading Day of such Conversion Period. In respect of any conversion during the Valuation Period for any Spin-Off, references within this Section 4.04(c) related to 10 consecutive Trading Days shall be deemed to be replaced, solely in respect of that conversion, with such lesser number of Trading Days as have elapsed from, and including, the Ex-Dividend Date for such Spin-Off to, but excluding, the relevant Conversion Date.

If any such dividend or distribution that constitutes a Spin-Off is declared but not paid or made, the Conversion Rate shall be decreased to be the Conversion Rate that would then be in effect if such distribution had not been declared.

For purposes of the second adjustment formula set forth in this Section 4.04(c), (i) the Closing Sale Price of any Capital Stock or similar equity interest shall be calculated in a manner analogous to that used to calculate the Closing Sale Price of the Common Stock in the definition of “Closing Sale Price” set forth in Section 1.01, (ii) whether a day is a Trading Day (and whether a day is a Scheduled Trading Day and whether a VWAP Market Disruption Event has occurred) for such Capital Stock or similar equity interest shall be determined in a manner analogous to that used to determine whether a day is a Trading Day (or whether a day is a Scheduled Trading Day and whether a VWAP Market Disruption Event has occurred) for the Common Stock, and (iii) whether a day is a Trading Day to be included in a Valuation Period shall be determined based on whether a day is a Trading Day for both the Common Stock and such Capital Stock or similar equity interest.

Subject to Section 4.04(f), for the purposes of this Section 4.04(c), rights, options or warrants distributed to all or substantially all holders of the Common Stock entitling them to acquire the Company’s Capital Stock or other securities, (either initially or under certain circumstances), which rights, options or warrants, until the occurrence of a specified event or events (a “Trigger Event”): (1) are deemed to be transferred with such shares of Common Stock; (2) are not exercisable; and (3) are also issued in respect of future issuances of Common Stock, shall be deemed not to have been distributed for purposes of this Section 4.04(c) (and no adjustment to the Conversion Rate under this Section 4.04(c) shall be required) until the occurrence of the earliest Trigger Event, whereupon such rights, options or warrants shall be deemed to have been distributed and an appropriate adjustment (if any is required) to the Conversion Rate shall be made under this Section 4.04(c). If any such rights, options or warrants, distributed prior to the first date of original issuance of the Initial Notes are subject to events, upon the occurrence of which such rights, options or warrants become exercisable to purchase different

securities, evidences of indebtedness or other assets, then the date of the occurrence of any and each such event shall be deemed to be the date of distribution and Record Date of such deemed distribution (in which case the original rights, options or warrants shall be deemed to terminate and expire on such date without exercise by any of the holders). In addition, in the event of any distribution or deemed distribution of rights, options or warrants, or any Trigger Event or other event (of the type described in the preceding sentence) with respect thereto that was counted for purposes of calculating a distribution amount for which an adjustment to the Conversion Rate under this Section 4.04(c) was made, (1) in the case of any such rights, options or warrants which shall all have been redeemed or purchased without exercise by any Holders thereof, upon such final purchase (x) the Conversion Rate shall be readjusted as if such rights, options or warrants had not been issued and (y) the Conversion Rate shall then again be readjusted to give effect to such distribution, deemed distribution or Trigger Event, as the case may be, as though it were a cash distribution, equal to the per share purchase price received by holders of Common Stock with respect to such rights, options or warrants (assuming each such holder had retained such rights, options or warrants), made to all holders of Common Stock as of the date of such purchase, and (2) in the case of such rights, options or warrants which shall have expired or been terminated without exercise by any holders thereof, the Conversion Rate shall be readjusted as if such rights and warrants had not been issued.

For purposes of Sections 4.04(a) through (c), if any dividend or distribution to which this Section 4.04(c) applies includes one or both of:

(A) a dividend or distribution of shares of Common Stock to which Section 4.04(a) also applies (the “Clause A Distribution”); or

(B) an issuance of rights, options or warrants entitling holders of the Common Stock to subscribe for or purchase shares of the Common Stock to which Section 4.04(b) also applies (the “Clause B Distribution”),

then (i) such dividend or distribution, other than the Clause A Distribution and the Clause B Distribution, shall be deemed to be a distribution to which this Section 4.04(c) applies (the “Clause C Distribution”) and any Conversion Rate adjustment required to be made under this Section 4.04(c) with respect to such Clause C Distribution shall be made, (ii) the Clause B Distribution, if any, shall be deemed to immediately follow the Clause C Distribution and any Conversion Rate adjustment required by Section 4.04(b) with respect thereto shall then be made, except that, if determined by the Company, (A) the “Record Date” of the Clause B Distribution and the Clause A Distribution, if any, shall be deemed to be the Record Date of the Clause C Distribution and (B) any shares of Common Stock included in the Clause A Distribution or the Clause B Distribution shall not be deemed to be “outstanding immediately prior to the Close of Business on such Record Date” within the meaning of Section 4.04(b), and (iii) the Clause A Distribution, if any, shall be deemed to immediately follow the Clause C Distribution or the Clause B Distribution, as the case may be, except that, if determined by the Company, (A) the “Record Date” of the Clause A Distribution and the Clause B Distribution, if any, shall

be deemed to be the Record Date of the Clause C Distribution, and (B) any shares of Common Stock included in the Clause A Distribution shall not be deemed to be “outstanding immediately prior to the Close of Business on such Record Date or such Effective Date” within the meaning of Section 4.04(a).

(d) If an Ex-Dividend Date occurs for any cash dividend or distribution to all or substantially all holders of the Common Stock (other than any dividend or distribution in connection with the liquidation, dissolution or winding-up of the Company), the Conversion Rate shall be increased based on the following formula:

CR1 = CR0 x	SP0
CR1 = CR0 x	SP0 - C

where,

CR0 =	the Conversion Rate in effect immediately prior to the Open of Business on the Ex-Dividend Date for such dividend or distribution;

CR1 =	the Conversion Rate in effect immediately after the Open of Business on the Ex-Dividend Date for such dividend or distribution;

SP0 =	the average of the Closing Sale Prices of the Common Stock over the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Ex-Dividend Date for such dividend or distribution; and

C =	the amount in cash per share that the Company pays or distributes to holders of the Common Stock.

Such increase shall become effective immediately after the Open of Business on the Ex-Dividend Date for such dividend or distribution. No adjustment pursuant to the above formula shall result in a decrease of the Conversion Rate. If such dividend or distribution is not so paid or made, the Conversion Rate shall be readjusted, effective as of the date the Board of Directors determines not to pay such dividend or not to make such distribution, to be the Conversion Rate that would then be in effect if such dividend or distribution had not been declared.

If “C” (as defined above) is equal to or greater than “SP0” (as defined above), in lieu of the foregoing increase, each Holder shall receive, for each $1,000 principal amount of Notes it holds, at the same time and upon the same terms as holders of shares of the Common Stock, without having to convert its Notes, the amount of cash that such Holder would have received if such Holder had owned a number of shares of Common Stock equal to the Conversion Rate in effect on the Record Date for such cash dividend or distribution.

(e) If the Company or any of its Subsidiaries make a payment in respect of a tender offer or exchange offer for the Common Stock, to the extent that the cash and value of any other consideration included in the payment per share of the Common Stock exceeds the average of the Closing Sale Prices of the Common Stock over the 10 consecutive Trading Day period commencing on, and including, the Trading Day next succeeding the last date on which tenders or exchanges may be made pursuant to such tender or exchange offer (the “Offer Expiration Date”), the Conversion Rate shall be increased based on the following formula:

CR1 = CR0 x	AC + (SP1 x OS1)
CR1 = CR0 x	OS0 x SP1

where,

CR0 =	the Conversion Rate in effect immediately prior to the Open of Business on the Trading Day next succeeding the Offer Expiration Date;

CR1 =	the Conversion Rate in effect immediately after the Open of Business on the Trading Day next succeeding the Offer Expiration Date;

AC =	the aggregate value of all cash and any other consideration (as determined in good faith by the Board of Directors) paid or payable for shares of Common Stock purchased in such tender or exchange offer;

OS0 =	the number of shares of Common Stock outstanding immediately prior to the expiration time of the tender or exchange offer on the Offer Expiration Date (prior to giving effect to the purchase of all shares accepted for purchase or exchange in such tender or exchange offer);

OS1 =	the number of shares of Common Stock outstanding immediately after the expiration time of the tender or exchange offer on the Offer Expiration Date (after giving effect to the purchase of all shares accepted for purchase or exchange in such tender or exchange offer); and

SP1 =	the average of the Closing Sale Prices of the Common Stock over the 10 consecutive Trading Day period commencing on, and including, the Trading Day next succeeding the Offer Expiration Date.

The adjustment to the Conversion Rate under the preceding paragraph shall be determined at the Close of Business on the tenth Trading Day immediately following, but excluding, the Offer Expiration Date but shall be given effect at the Open of Business on the Trading Day next succeeding the Offer Expiration Date. If the Trading Day next succeeding the Offer Expiration Date is less than 10 Trading Days prior to, and including, the end of the Conversion Period in respect of any conversion, references within this Section 4.04(e) to 10 Trading Days shall be deemed to be replaced, solely in respect of that conversion, with such lesser number of Trading Days as have elapsed from, and

including, the Trading Day next succeeding the Offer Expiration Date to, and including, the last VWAP Trading Day of such Conversion Period. In respect of any conversion during the 10 Trading Days commencing on the Trading Day next succeeding the Offer Expiration Date, references within this Section 4.04(e) to 10 Trading Days shall be deemed to be replaced, solely in respect of that conversion, with such lesser number of Trading Days as have elapsed from, and including, the Trading Day next succeeding the Offer Expiration Date to, but excluding, the relevant Conversion Date. No adjustment pursuant to the above formula shall result in a decrease of the Conversion Rate.

(f) Special Settlement Provisions. (i) Notwithstanding anything to the contrary herein, if a Holder converts a Note and:

(A) Combination Settlement is applicable to such Note and shares of Common Stock are deliverable to settle the Daily Net Share Number for a given Trading Day within the Conversion Period applicable to such Note;

(B) any distribution, transaction or event described in Sections 4.04(a) through (e) has not yet resulted in an adjustment to the applicable Conversion Rate on such Trading Day; and

(C) the shares of Common Stock deliverable in respect of such Trading Day are not entitled to participate in the relevant distribution or transaction (because such shares of Common Stock were not held on a related Record Date or otherwise),

then the Company shall adjust the number of shares of Common Stock delivered in respect of the relevant Trading Day to reflect the relevant distribution or transaction.

If a Holder converts a Note and:

(A) Physical Settlement, is applicable to such Note;

(B) any distribution or transaction described in Sections 4.04(a) through (e) has not yet resulted in an adjustment to the applicable Conversion Rate on a given Conversion Date; and

(C) the shares of Common Stock deliverable on settlement of the related conversion are not entitled to participate in the relevant distribution or transaction (because such shares of Common Stock were not held on a related Record Date or otherwise),

then the Company shall adjust the number of shares of Common Stock delivered in respect of such conversion to reflect the relevant distribution or transaction.

(ii) If a Conversion Rate adjustment becomes effective on any Ex-Dividend Date as described above, and a Holder that has converted its Notes on or after such Ex-Dividend Date and on or prior to the related Record Date

would be treated as the record holder of shares of Common Stock as of the related Conversion Date pursuant to Section 4.03 based on an adjusted Conversion Rate for such Ex-Dividend Date, then, notwithstanding the foregoing Conversion Rate adjustment provisions, the Conversion Rate adjustment relating to such Ex-Dividend Date shall not be made for such converting Holder. Instead, such Holder shall be treated as if such Holder were the record owner of the shares of Common Stock on an unadjusted basis and participate in the related dividend, distribution or other event giving rise to such adjustment.

(g) Poison Pill. If a Holder converts a Note, to the extent that the Company has a rights plan in effect, on the Conversion Date applicable to such Note, the Holder converting such Note shall receive, in addition to any shares of Common Stock otherwise received in connection with such conversion on such Conversion Date the rights under the rights plan, unless prior to such Conversion Date the rights have separated from the Common Stock, in which case, and only in such case, the Conversion Rate shall be adjusted at the time of separation as if the Company distributed to all holders of the Common Stock, Distributed Property as described in Section 4.04(c), subject to readjustment in the event of the expiration, termination of such rights.

(h) Deferral of Adjustments. Notwithstanding anything to the contrary herein, the Company shall not be required to adjust the Conversion Rate unless such adjustment would require an increase or decrease of at least one percent; provided, however, that any such minor adjustments that are not required to be made shall be carried forward and taken into account in any subsequent adjustment, and provided, further, that any such adjustment of less than one percent that has not been made shall be made (x) upon any repurchase of Notes by the Company at the option of Holder pursuant to Article 3, (y) on each of the VWAP Trading Days within any Conversion Period and (z) upon any Conversion Date. In addition, the Company shall not account for such deferrals when determining whether any of the conditions to conversion have been satisfied or what number of shares of Common Stock a Holder would have held on a given day had it converted its Notes.

(i) Limitation on Adjustments. Except as stated in this Section 4.04, the Company shall not adjust the Conversion Rate for the issuance of shares of Common Stock or any securities convertible into or exchangeable for shares of Common Stock or the right to purchase shares of Common Stock or such convertible or exchangeable securities. If, however, the application of the formulas in Sections 4.04(a) through (e) would result in a decrease in the Conversion Rate, then, except to the extent of any readjustment to the Conversion Rate, no adjustment to the Conversion Rate shall be made (other than as a result of a reverse share split or share combination).

(j) For purposes of this Section 4.04, the number of shares of Common Stock at any time outstanding shall not include shares held in the treasury of the Company so long as the Company does not pay any dividend or make any distribution on shares of Common Stock held in the treasury of the Company, but shall include

shares issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock.

Section 4.05 Discretionary and Voluntary Adjustments.

(a) Discretionary Adjustments. Whenever any provision of the Indenture requires the Company to calculate the Closing Sale Prices, Daily VWAPs, Daily Conversion Values, Daily Settlement Amounts or the Stock Price for purposes of a Make-Whole Adjustment Event over a span of multiple days, the Board of Directors shall make appropriate adjustments to account for any adjustment to the Conversion Rate that becomes effective, or any event requiring an adjustment to the Conversion Rate where the Ex-Dividend Date, Offer Expiration Date or Effective Date of the event occurs, at any time during the period from which such Closing Sale Prices, Daily VWAPs, Daily Conversion Values, Daily Settlement Amounts or Stock Prices are to be calculated.

(b) Voluntary Adjustments. To the extent permitted by applicable law and applicable requirements of the Exchange and any other securities exchange on which the Common Stock is then listed, the Company is permitted to increase the Conversion Rate of the Notes by any amount for a period of at least 20 Business Days if such increase is irrevocable for such period and the Board of Directors determines that such increase would be in the Company’s best interest. The Company may also (but is not required to) increase the Conversion Rate to avoid or diminish income tax to holders of Common Stock or rights to purchase shares of Common Stock in connection with a dividend or distribution of shares (or rights to acquire shares) or similar event.

Section 4.06 Adjustment to Conversion Rate Upon Conversion in Connection with a Make-Whole Adjustment Event.

(a) Increase in the Conversion Rate. If a Make-Whole Adjustment Event occurs and a Holder elects to convert its Notes in connection with such Make-Whole Adjustment Event, then the Company shall, to the extent provided herein, increase the Conversion Rate for the Notes so surrendered for conversion by a number of additional shares of Common Stock (the “Additional Shares”), as described in this Section 4.06. A conversion of Notes shall be deemed for these purposes to be “in connection with” a Make-Whole Adjustment Event if the relevant Conversion Notice is received by the Conversion Agent during the period from, and including, the Effective Date of the Make-Whole Adjustment Event up to, and including, the Close of Business on the Business Day immediately prior to the related Fundamental Change Purchase Date or, if such Make-Whole Adjustment Event is not also a Fundamental Change, the 40th Scheduled Trading Day immediately following the Effective Date for such Make-Whole Adjustment Event (such period, the “Make-Whole Adjustment Event Period”).

(b) Cash Mergers. Notwithstanding anything to the contrary herein, if the consideration paid to holders of the Common Stock in any Make-Whole Adjustment Event described in clause (2) of the definition of “Fundamental Change” is comprised

entirely of cash, then, for any conversion of Notes following the Effective Date of such Make-Whole Adjustment Event, the payment and delivery obligations upon the conversion of a Note shall be calculated based solely on the Stock Price for such Make-Whole Adjustment Event and shall be deemed to be an amount equal to the applicable Conversion Rate (including any adjustment as described in this Section 4.06) multiplied by such Stock Price. In such event, the Company’s conversion obligation shall be determined and paid to Holders in cash on the tenth Business Day following the applicable Conversion Date. Otherwise, the Company shall settle any conversion of the Notes following the Effective Date for a Make-Whole Adjustment Event in accordance with Section 4.03 (but subject to Section 4.04).

(c) Determining the Number of Additional Shares. The number of Additional Shares, if any, by which the Conversion Rate shall be increased for a Holder that converts its Notes in connection with a Make-Whole Adjustment Event shall be determined by reference to the table attached as Schedule A, based on the Effective Date and the price (the “Stock Price”) paid (or deemed paid) per share of Common Stock in the Make-Whole Adjustment Event as determined under the two immediately following sentences. In the event that the holders of the Common Stock receive only cash in a Make-Whole Adjustment Event described in clause (2) of the definition of “Fundamental Change,” the Stock Price shall be the cash amount paid per share of Common Stock. Otherwise, the Stock Price shall be the average of the Closing Sale Prices of the Common Stock over the five consecutive Trading Day period ending on the Trading Day immediately preceding the Effective Date of the Make-Whole Adjustment Event.

(d) Interpolation and Limits. The exact Stock Prices and Effective Dates may not be set forth in the table in Schedule A, in which case:

(i) If the Stock Price is between two Stock Prices in the table or the Effective Date is between two dates in the table, the number of Additional Shares shall be determined by a straight-line interpolation between the number of Additional Shares set forth for the next higher and next lower Stock Prices and the earlier and later dates, as applicable, based on a 365-day year.

(ii) If the Stock Price is greater than $200.00 per share (subject to adjustment in the same manner as the Stock Prices set forth in the column headings of the table in Schedule A), no Additional Shares shall be added to the Conversion Rate.

(iii) If the Stock Price is less than $26.025 per share (subject to adjustments in the same manner as the Stock Prices set forth in the column headings of the table in Schedule A), no Additional Shares shall be added to the Conversion Rate.

Notwithstanding the foregoing, in no event shall the Conversion Rate be increased on account of a Make-Whole Adjustment Event to exceed 38.4245 shares of Common Stock per

$1,000 principal amount of Notes, subject to adjustments in the same manner as the Conversion Rate is required to be adjusted as set forth in Section 4.04.

(iv) The Stock Prices set forth in the column headings of the table in Schedule A shall be adjusted as of any date on which the Conversion Rate of the Notes is otherwise required to be adjusted. The adjusted Stock Prices shall equal the Stock Prices applicable immediately prior to such adjustment, multiplied by a fraction, the numerator of which is the Conversion Rate immediately prior to such adjustment giving rise to the Stock Price adjustment and the denominator of which is the Conversion Rate as so adjusted. The number of Additional Shares set forth in such table shall be adjusted in the same manner and at the same time as the Conversion Rate is required to be adjusted as set forth in Section 4.04.

(e) Notices. The Company shall notify the Holders, the Trustee and the Conversion Agent (if other than the Trustee) in writing of the anticipated Effective Date of any Make-Whole Adjustment Event and issue a press release announcing such anticipated Effective Date as soon as practicable after determining such anticipated Effective Date (and make the press release available on the Company website). The Company shall use its commercially reasonable efforts to give notice to Holders of the anticipated Effective Date for a Make-Whole Adjustment Event not less than 50 Scheduled Trading Days prior to such anticipated Effective Date.

Section 4.07 Effect of Recapitalization, Reclassification, Consolidation, Merger or Sale.

(a) Merger Events. In the case of:

(i) any recapitalization, reclassification or change of the Common Stock (other than as a result of a subdivision or combination for which an adjustment was made pursuant to Section 4.04(a));

(ii) a consolidation, merger, combination or binding share exchange involving the Company; or

(iii) a sale, assignment, conveyance, transfer, lease or other disposition to a third party of the consolidated assets of the Company and its Subsidiaries as an entirety or substantially as an entirety;

and, in each case, as a result of which the Common Stock would be converted into, or exchanged for, common stock, other securities, other property or assets (including cash or any combination thereof) (any such event, a “Merger Event,” any such common stock, other securities, other property or assets (including cash or any combination thereof), “Reference Property,” and (i) the amount and kind of Reference Property that a holder of one share of Common Stock is entitled to receive in the applicable Merger Event, or (ii) if as a result of the applicable Merger Event, each share of Common Stock is converted into, or exchanged for, the right to receive

more than a single type of consideration (determined based in part upon any form of stockholder election), the per share of Common Stock weighted average of the amounts and kinds of Reference Property received by the holders of Common Stock that affirmatively make such an election, a “Unit of Reference Property”), then, at the effective time of such Merger Event, the right to convert each $1,000 principal amount of Notes into a number of shares of the Common Stock equal to the Conversion Rate in effect immediately prior to such Merger Event shall, without the consent of the Holders, be changed into a right to convert each $1,000 principal amount of Notes into or based on a number of Units of Reference Property equal to the Conversion Rate in effect immediately prior to such Merger Event, and, prior to or at the effective time of such Merger Event, the Company or the successor or purchasing person, as the case may be, shall execute with the Trustee a supplemental indenture providing for such change in the right to convert each $1,000 principal amount of Notes; provided, however, that at and after the effective time of the Merger Event, (i) the Company shall continue to have the right to determine the Settlement Method applicable to any conversion of Notes, unless it has previously irrevocably elected Combination Settlement with a particular Specified Dollar Amount, (ii) any amount otherwise payable in cash upon conversion of the Notes shall continue to be payable in cash under Section 4.03, (iii) the number of shares of Common Stock that the Company would have been required to deliver upon conversion of the Notes in accordance with Section 4.03 and 4.06 shall instead be deliverable in Units of Reference Property and (iv) the Daily VWAP shall, to the extent reasonably possible, be calculated based on the value of a Unit of Reference Property.

The Company shall not become a party to any Merger Event unless its terms are consistent with this Section 4.07. Such supplemental indenture described in the immediately preceding paragraph shall provide for adjustments which shall be as nearly equivalent to the adjustments provided for in this Article 4 in the judgment of the Board of Directors or the board of directors of the successor person. If, in the case of any such Merger Event, the Reference Property receivable thereupon by a holder of Common Stock includes shares of stock, securities or other property or assets (including cash or any combination thereof) of a person other than the successor or purchasing person, as the case may be, in such Merger Event, then such indenture shall also be executed by such other person.

(b) Notice of Supplemental Indentures. The Company shall cause written notice of the execution of such supplemental indenture to be given to each Holder in accordance with Section 12.08(c) within 20 calendar days after execution thereof. Failure to deliver such notice shall not affect the legality or validity of such supplemental indenture. The above provisions of this Section 4.07 shall similarly apply to successive Merger Events.

(c) Prior Notice. In addition, at least 10 Scheduled Trading Days before any Merger Event, the Company shall give notice to Holders of such Merger Event, or, if the Company has not publicly announced such Merger Event at such time, as promptly as practicable after publicly announcing such Merger Event. In any such notice, the Company shall also specify the composition of the Unit of Reference Property for such Merger Event, or, if the Company has not determined the composition of such Unit of Reference Property at such time, the Company shall provide an additional written notice

to Holders that states the composition of such Unit of Reference Property as promptly as practicable after determining its composition.

Section 4.08 Certain Covenants.

(a) Reservation of Shares. To the extent necessary to satisfy its obligations under this Supplemental Indenture, prior to issuing any shares of Common Stock, the Company shall reserve out of its authorized but unissued shares of Common Stock a sufficient number of shares of Common Stock to permit the conversion of the Notes.

(b) Certain other Covenants. The Company covenants that all shares of Common Stock that may be issued upon conversion of Notes shall be issued in book-entry format, shall be newly issued shares or treasury shares, shall be duly authorized, validly issued, fully paid and non-assessable and shall be free from preemptive rights and free from any tax, lien or charge (other than those created by the Holder or due to a change in registered owner). The Company shall list or cause to have quoted any shares of Common Stock to be issued upon conversion of Notes on each national securities exchange or over-the-counter or other domestic market on which the Common Stock is then listed or quoted.

Section 4.09 Responsibility of Trustee. The Trustee and any Conversion Agent shall not at any time be under any duty or responsibility to any Holder of Notes or any other person to determine or calculate the Conversion Rate, to determine whether any facts exist which may require any adjustment of the Conversion Rate, or to confirm the accuracy of any such adjustment when made or the appropriateness of the method employed, or herein or in any supplemental indenture provided to be employed, in making the same. The Trustee and any Conversion Agent shall not be accountable with respect to the validity or value (or the kind or amount) of any shares of Common Stock or of any other securities or property that may at any time be issued or delivered upon the conversion of any Notes; and the Trustee and the Conversion Agent make no representations with respect thereto. Neither the Trustee nor any Conversion Agent shall be responsible for any failure of the Company to issue, transfer or deliver any shares of Common Stock or stock certificates or other securities or property or cash upon the surrender of any Notes for the purpose of conversion or to comply with any of the duties, responsibilities or covenants of the Company contained in this Article 4. The rights, privileges, protections, immunities and benefits given to the Trustee, including without limitation its right to be compensated, reimbursed and indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, including its capacity as Conversion Agent.

Section 4.10 Notice of Adjustment to the Trustee. Whenever the Conversion Rate is adjusted as herein provided, the Company shall promptly file with the Trustee and any Conversion Agent (if other than the Trustee) an Officers’ Certificate setting forth the Conversion Rate after such adjustment, a brief statement of the facts requiring such adjustment and the calculations of the Conversion Rate. Unless and until a Responsible Officer of the Trustee shall have received such Officers’ Certificate, the Trustee shall not be deemed to have knowledge of any adjustment of the Conversion Rate and may assume that the last Conversion Rate of which it

has knowledge is still in effect. Promptly after delivery of such certificate, the Company shall prepare a notice of such adjustment of the Conversion Rate setting forth the adjusted Conversion Rate and the date as of which each adjustment becomes effective and shall deliver such notice of such adjustment of the Conversion Rate to the Holder of each Note in accordance with Section 12.08(c) within 20 days after execution thereof. Failure to deliver such notice shall not affect the legality, effectiveness or validity of any such adjustment and shall not be an Event of Default under this Supplemental Indenture.

Section 4.11 Notice to Holders.

(a) Notice to Holders Prior to Certain Actions. The Company shall deliver written notices of the events specified below at the times specified below and containing the information specified below unless, in each case, (i) pursuant to this Supplemental Indenture, the Company is already required to deliver notice of such event containing at least the information specified below at an earlier time or (ii) the Company, at the time it is required to deliver a notice, does not have knowledge of all of the information required to be included in such notice, in which case, the Company shall (A) deliver notice at such time containing only the information that it has knowledge of at such time (if it has knowledge of any such information at such time), and (B) promptly upon obtaining knowledge of any such information not already included in a notice delivered by the Company, deliver notice to each Holder containing such information. In each case, the failure by the Company to give such notice, or any defect therein, shall not affect the legality or validity of such event.

(i) Issuances, Distributions, and Dividends and Distributions. If the Company (A) announces any issuance of any rights, options or warrants that would require an adjustment in the Conversion Rate pursuant to Section 4.04(b); (B) authorizes any distribution that would require an adjustment in the Conversion Rate pursuant to Section 4.04(c) (including any separation of rights from the Common Stock described in Section 4.04(f)); or (C) announces any dividend or distribution that would require an adjustment in the Conversion Rate pursuant to Section 4.04(d), then the Company shall deliver to the Holders at least 50 Scheduled Trading Days prior to the Ex-Dividend Date for such issuance, dividend or distribution, notice describing such issuance, dividend or distribution, as the case may be, and stating the expected Ex-Dividend Date and Record Date for such issuance, distribution, dividend or distribution, as the case may be. In addition, the Company shall deliver to the Holders written notice if the consideration included in such issuance, dividend or distribution, or the Ex-Dividend Date or Record Date of such issuance, dividend or distribution, as the case may be, changes.

(ii) Tender and Exchange Offers. If the Company announces any tender or exchange offer that could require an adjustment in the Conversion Rate pursuant to Section 4.04(e), the Company shall deliver to the Holders on the day it announces such tender or exchange offer, and, if the Company is required to file with the Commission a Schedule TO in connection with such

tender or exchange offer, an additional written notice (i) when the Company first files such Schedule TO, which notice shall include the address at which such Schedule TO is available on the Commission’s EDGAR system (or any successor thereto), and (ii) whenever the Company files an amendment to such Schedule TO, which notice shall include the address at which such amendment is available on the Commission’s EDGAR system (or any successor thereto).

If the Company increases the Conversion Rate pursuant to Section 4.04(b), the Company shall deliver notice to the Holders at least 15 calendar days prior to the date on which such increase shall become effective, which notice shall state the date on which such increase shall become effective and the amount by which the Conversion Rate shall be increased.

(iv) Dissolutions, Liquidations and Winding-Ups. If there is a voluntary or involuntary dissolution, liquidation or winding-up of the Company, the Company shall deliver notice to the Holders at promptly as possible, but in any event at least 50 Scheduled Trading Days prior to the earlier of (i) the date on which such dissolution, liquidation or winding-up, as the case may be, is expected to become effective or occur, and (ii) the date as of which it is expected that holders of Common Stock of record shall be entitled to exchange their Common Stock for securities or other property deliverable upon such dissolution, liquidation or winding-up, as the case may be, which notice shall state the expected effective date and Record Date for such event, as applicable, and the amount and kind of property that a holder of one share of the Common Stock is expected to be entitled, or may elect, to receive in such event. The Company shall deliver an additional written notice to Holders, as promptly as practicable, whenever the expected effective date or Record Date, as applicable, or the amount and kind of property that a holder of one share of the Common Stock can expect to be entitled to receive in such event, changes.

(b) Notices After Certain Actions and Events. Whenever an adjustment to the Conversion Rate becomes effective pursuant to Section 4.04, 4.05 or 4.06, the Company shall (i) promptly deliver to the Conversion Agent and the Trustee an Officers’ Certificate stating that such adjustment has become effective, the Conversion Rate, the manner in which the adjustment was computed and describing the facts upon which the adjustment was based (and unless and until a Responsible Officer of the Trustee shall have received such Officers’ Certificate, the Trustee shall not be deemed to have knowledge of any adjustment of the Conversion Rate and may assume that the last Conversion Rate of which it has knowledge is still in effect) and (ii) issue a press release (and make such press release available on the Company’s website) stating that such adjustment has become effective and the Conversion Rate or conversion privilege as adjusted. Failure to give any such notice, or any defect therein, shall not affect the validity of any such adjustment.

Section 6.05 Control by Majority. Subject to the Trustee’s duties in the case of an Event of Default, the Trustee shall not be obligated to exercise any of its rights or powers at the request of the Holders unless the Holders have offered to the Trustee indemnity or security satisfactory to it against any loss, liability or expense. Subject to this Supplemental Indenture, applicable law and the Trustee’s indemnification, the Holders of a majority in aggregate principal amount of the Outstanding Notes may direct in writing the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee with respect to the Notes.

Section 6.06 Limitation on Suits. Subject to Section 6.07, no Holder shall have any right to institute any proceeding under this Supplemental Indenture, or for the appointment of a receiver or Trustee, or for any other remedy under this Supplemental Indenture or with respect to the Notes unless:

No one or more Holders shall have any right in any manner whatever by virtue of or by availing of any provision of this Supplemental Indenture to affect, disturb, prejudice the rights of any other Holder, or to obtain or seek to obtain priority over or preference to any other such Holder, or to enforce any right under this Supplemental Indenture, except in the manner herein provided and for the equal, ratable and common benefit of all Holders (except as otherwise provided herein). For the protection and enforcement of this Section 6.06, each and every Holder and the Trustee shall be entitled to such relief as can be given either at law or in equity.

Section 6.07 Rights of Holders to Receive Payment and to Convert. Notwithstanding anything to the contrary elsewhere in this Supplemental Indenture, the above limitations set forth under Section 6.06 do not apply to a suit instituted by a Holder for the enforcement of a payment of the principal of, or any interest on, any Note, on or after the applicable due date, the right to convert the Note or to receive the Settlement Amounts due upon conversion in accordance with Article 4, or the right of a beneficial owner to exchange its beneficial interest in a Global Note for a Physical Note if an Event of Default has occurred and is continuing in accordance with Section 2.11.

If an Event of Default specified in Section 6.01(a), 6.01(b), 6.01(c) or 6.01(d) occurs and is continuing, the Trustee is authorized to recover judgment in its own name and as trustee of an express trust against the Company for the whole amount of principal of, interest on, the Fundamental Change Purchase Price with respect to, the Settlement Amounts due upon the conversion of the Notes and such further amount as is sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, as well as any other amounts that may be due hereunder

Section 6.09 Trustee May Enforce Claims Without Possession of Notes. All rights of action and claims under this Supplemental Indenture or the Notes may be prosecuted and enforced by the Trustee without the possession of any of the Notes or the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the compensation, and reasonable expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders in respect of which such judgment has been recovered.

Section 6.10 Trustee May File Proofs of Claim. The Trustee is authorized to file such proofs of claim and other papers or documents as may be necessary or advisable to have the claims of the Trustee and the Holders allowed in any judicial proceedings relative to the Company, its creditors or its property and, unless prohibited by law or applicable regulations, shall be entitled to collect, receive and distribute any money or other property payable or deliverable on any such claims, and any custodian in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee, and, in the event that the Trustee consents to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee hereunder. To the extent that the payment of any such compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee hereunder out of the estate in any such proceeding, shall be denied for any reason, payment of the same shall be secured by a lien on, and is paid out of, any and all distributions, dividends, money, securities and other properties that the Holders may be entitled to receive in such proceeding, whether in liquidation or under any plan of reorganization or arrangement or otherwise. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to, or to accept or to adopt on behalf of any Holder, any plan of reorganization, arrangement, adjustment or

composition affecting the Notes or the rights of any Holder, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

Section 6.11 Restoration of Rights and Remedies. If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy under this Supplemental Indenture and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and in every such case, subject to any determination in such proceeding, the Company, the Trustee and the Holders shall be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Trustee and the Holders shall continue as though no such proceeding had been instituted.

Section 6.12 Rights and Remedies Cumulative. Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Notes in Section 2.09, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy.

Section 6.13 Delay or Omission Not a Waiver. No delay or omission of the Trustee or of any Holder to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article 6 or by law to the Trustee or to the Holders may be exercised from time to time and as often as may be deemed expedient by the Trustee (subject to the limitations contained in this Supplemental Indenture) or by the Holders, as the case may be.

Section 6.14 Priorities. If the Trustee collects any money or property pursuant to this Article 6, it shall pay out the money or property in the following order:

FIRST: to the Trustee, its agents and attorneys for amounts due under Section 11.07, including payment of all compensation, expenses and liabilities incurred, and all advances made, by the Trustee and the costs and expenses of collection;

SECOND: to the Holders, for any amounts due and unpaid on the principal of, accrued and unpaid interest on, the Fundamental Change Purchase Price with respect to, and any cash due upon conversion of, any Note, without preference or priority of any kind, according to such amounts due and payable on all of the Notes; and

THIRD: the balance, if any, to the Company or to such other party as a court of competent jurisdiction directs.

The Trustee may fix a record date and payment date for any payment to the Holders pursuant to this Section 6.14. If the Trustee so fixes a record date and a payment date, at least 15

calendar days prior to such record date, the Trustee shall deliver to each Holder a written notice, which notice shall state such record date, such payment date and the amount of such payment.

Section 6.15 Undertaking for Costs. All parties to this Supplemental Indenture agree, and each Holder, by such Holder’s acceptance of a Note, shall be deemed to have agreed, that any court may in its discretion require, in any suit for the enforcement of any right or remedy under this Supplemental Indenture, or in any suit against the Trustee for any action taken or omitted by it as Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; provided, however, that the provisions of this Section 6.15 shall not apply to (i) any suit instituted by the Trustee, (ii) any suit instituted by any Holder, or group of Holders, holding in the aggregate more than 10% in aggregate principal amount of the Notes then Outstanding, (iii) any suit instituted by any Holder for the enforcement of the payment of the principal (including the Fundamental Change Purchase Price) of, or any interest on any Note on or after the applicable due date expressed or provided for in this Supplemental Indenture, (iv) any suit for the enforcement of the right to convert any Note or to receive the Settlement Amounts due upon conversion of any Note in accordance with the provisions of Article 4, or (v) any suit for the enforcement of the right of a beneficial owner to exchange its beneficial interest in a Global Note for a Physical Note if an Event of Default has occurred and is continuing in accordance with Section 2.11.

Section 6.16 Waiver of Stay, Extension and Usury Laws. The Company covenants that, to the extent that it may lawfully do so, it shall not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law wherever enacted, now or at any time hereafter in force, that may affect the covenants or the performance of this Supplemental Indenture; and the Company, to the extent that it may lawfully do so, hereby expressly waives all benefit or advantage of any such law, and covenants that it shall not, by resort to any such law, hinder, delay or impede the execution of any power herein granted to the Trustee, but shall instead suffer and permit the execution of every such power as though no such law has been enacted.

Section 6.17 Notices from the Trustee. If a Default occurs and is continuing and is known to the Trustee, the Trustee must mail notice of such Default to each Holder within 90 days after it occurs. Except in the case of a Default in the payment of the principal of or interest on, any Note or of a Default in the delivery of the Settlement Amounts due upon conversion of any Note, the Trustee may withhold notice if and so long as the Trustee in good faith determines that withholding notice is in the interests of the Holders.

ARTICLE 7.
SATISFACTION AND DISCHARGE; NO DEFEASANCE

Notwithstanding anything to the contrary in the Indenture or the Notes, this Article 7 shall apply to the Notes in lieu of Article IV of the Base Indenture. When (i) (a) the Company shall deliver to the Trustee for cancellation all

Notes theretofore authenticated (other than any Notes that have been destroyed, lost or stolen and in lieu of or in substitution for which other Notes shall have been authenticated and delivered) and not theretofore canceled, or (b) all the Notes not theretofore canceled or delivered to the Trustee for cancellation shall have become due and payable (whether on the Maturity Date, on any Fundamental Change Purchase Date, upon conversion or otherwise) and the Company shall deposit with the Trustee, in trust, or deliver to the Holders, as applicable, an amount of cash (and, to the extent applicable, deliver to the Holders a number of shares of Common Stock to satisfy the Company’s obligations with respect to outstanding conversions) sufficient to pay all amounts due on all of such Notes (other than any Notes that shall have been mutilated, destroyed, lost or stolen and in lieu of or in substitution for which other Notes shall have been authenticated and delivered) not theretofore canceled or delivered to the Trustee for cancellation, including principal and interest due, accompanied, except in the event the Notes are due and payable solely in cash at the Maturity Date or upon an earlier Fundamental Change Purchase Date, by a verification report as to the sufficiency of the deposited amount from an independent certified accountant or other financial professional satisfactory to the Trustee, and the Company shall have paid or cause to be paid all other sums payable hereunder by the Company, and (ii) the Company has delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent in this Supplemental Indenture provided for relating to the satisfaction and discharge of this Supplemental Indenture have been complied with, then this Supplemental Indenture shall cease to be of further effect (except as to (A) rights hereunder of Holders to receive all amounts owing upon the Notes and the other rights, duties and obligations of Holders, as beneficiaries hereof with respect to the amounts, if any, so deposited with the Trustee and (B) the rights, obligations, indemnities and immunities of the Trustee hereunder and the obligations of the Company in respect thereof), and the Trustee, on written demand of the Company accompanied by an Officers’ Certificate and an Opinion of Counsel and at the cost and expense of the Company, shall execute instruments acknowledging satisfaction and discharge of this Supplemental Indenture. Notwithstanding the foregoing, the Company hereby agrees to reimburse the Trustee for any reasonable costs or expenses thereafter reasonably incurred by the Trustee, including the fees and expenses of its counsel, and to compensate the Trustee for any services thereafter reasonably and properly rendered by the Trustee in connection with this Supplemental Indenture or the Notes.

Section 7.02 Deposited Monies to Be Held in Trust by Trustee. Subject to Section 7.04, all monies deposited with the Trustee pursuant to Section 7.01 shall be held in trust for the sole benefit of the Holders of the Notes, and such monies and shall be applied by the Trustee to the payment, either directly or through any Paying Agent (including the Company if acting as its own Paying Agent), to the Holders of the particular Notes for the payment of all sums or amounts due and to become due thereon for principal and interest, if any.

Section 7.03 Paying Agent to Repay Monies Held. Upon the satisfaction and discharge of this Supplemental Indenture, all excess monies then held by any Paying Agent (if other than the Trustee) shall, upon written request of the Company, be repaid to it or paid to the Trustee, and thereupon such Paying Agent shall be released from all further liability with respect to such amounts.

Section 7.04 Return of Unclaimed Monies. Subject to the requirements of applicable law, any monies deposited with or paid to the Trustee for payment of the principal of or interest, if any, on the Notes and not applied but remaining unclaimed by the Holders of the Notes for two years after the date upon which the principal of or interest, if any, on such Notes, as the case may be, shall have become due and payable, shall be repaid to the Company by the Trustee on written demand, and all liability of the Trustee shall thereupon cease with respect to such monies; and the Holders shall thereafter look only to the Company for any payment that such Holder may be entitled to collect unless an applicable abandoned property law designates another person.

Section 7.05 Reinstatement. If the Trustee or the Paying Agent is unable to apply any monies in accordance with Section 7.02 by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Company’s obligations under this Supplemental Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 7.01 until such time as the Trustee or the Paying Agent is permitted to apply all such amounts in accordance with Section 7.02; provided, however, that if the Company makes any payment of interest on, principal of or delivery in respect of any Note following the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Notes to receive such payment from the monies held by the Trustee or Paying Agent.

ARTICLE 9.
SUCCESSOR COMPANY

Notwithstanding anything to the contrary in the Indenture or the Notes, this Article 9 shall apply to the Notes in lieu of Article VIII of the Base Indenture.

Section 9.01 Company May Consolidate, Etc. on Certain Terms. Subject to the provisions of Section 9.03, the Company shall not consolidate with, enter into a binding share exchange with, or merge with or into, another Person or sell, assign, convey, transfer, lease or

otherwise dispose of its properties and assets substantially as an entirety to another Person, unless:

(a) the resulting, surviving transferee or successor Person (the “Successor Company”), if any, is a corporation organized and existing under the laws of the U.S., any state of the U.S. or the District of Columbia and the Successor Company, if any, expressly assumes, by supplemental indenture, executed and delivered to the Trustee, all of the obligations of the Company under the Notes and this Supplemental Indenture;

(b) immediately after giving effect to such transaction, no Default or Event of Default shall have occurred and be continuing under this Supplemental Indenture with respect to the Notes;

(c) if, as a result of any such transaction, the Notes become convertible pursuant to the terms of this Supplemental Indenture into Common Stock or other securities issued by a third party (subject to Section 4.03), such third party fully and unconditionally guarantees all obligations of the Company or such Successor Company under the Notes and this Supplemental Indenture; and

(d) all other conditions specified in this Article 9 are met.

Upon any such consolidation, merger, binding share exchange, sale, assignment, conveyance, transfer, lease or other disposition to another Person, the Successor Company (if not the Company) shall succeed to, and may exercise every right and power of the Company under this Supplemental Indenture, and the Company shall be discharged from its obligations under the Notes and this Supplemental Indenture except in the case of any such lease.

For purposes of this Section 9.01, any sale, assignment, conveyance, transfer, lease or other disposition of the properties and assets of one or more Subsidiaries of the Company that would, if the Company held such properties and assets directly, have constituted the sale, assignment, conveyance, transfer, lease or disposition of the properties and assets of the Company substantially as an entirety shall be treated as such under this Supplemental Indenture.

Section 9.02 Successor Corporation to Be Substituted. In case of any such consolidation, merger, binding share exchange, sale, assignment, conveyance, transfer, lease or other disposition to another Person and upon the assumption by the Successor Company (if other than the Company), by supplemental indenture, executed and delivered to the Trustee, of the due and punctual payment of the principal of and accrued and unpaid interest, if any, on, all of the Notes, the due and punctual delivery of any Settlement Amount due upon conversion of the Notes, the due and punctual payment of the Fundamental Change Purchase Price, if any, and the due and punctual performance of all of the covenants and conditions of this Supplemental Indenture to be performed by the Company under this Supplemental Indenture, such Successor Company shall succeed to and be substituted for, and may exercise every right and power of, the Company under this Supplemental Indenture, with the same effect as if it had been named herein as the party of the first part; provided, however, that in the case of a sale, assignment, conveyance, transfer, lease or other disposition to one or more of its Subsidiaries of all or

substantially all of the properties and assets of the Company, the Notes shall remain convertible based on the Settlement Amount, in accordance with Section 4.03, but subject to adjustment (if any) in accordance with Section 4.06. Such Successor Company thereupon may cause to be signed, and may issue either in its own name or in the name of the Company any or all of the Notes issuable hereunder which theretofore shall not have been signed by the Company and delivered to the Trustee; and, upon receipt of a Company Order of such Successor Company instead of the Company and subject to all the terms, conditions and limitations in this Supplemental Indenture prescribed, the Trustee shall authenticate and shall deliver, or cause to be authenticated and delivered, any Notes that previously shall have been signed and delivered by the Officers of the Company to the Trustee for authentication, and any Notes that such Successor Company thereafter shall cause to be signed and delivered to the Trustee for that purpose. All the Notes so issued shall in all respects have the same legal rank and benefit under this Supplemental Indenture as the Notes theretofore or thereafter issued in accordance with the terms of this Supplemental Indenture as though all of such Notes had been issued at the date of the execution hereof. In the event of such consolidation, merger, binding share exchange, sale, assignment, conveyance, transfer or other disposition to another Person (but not in the case of a lease), the Person named as the “Company” in the first paragraph of this Supplemental Indenture or any successor that shall thereafter have become such in the manner prescribed in this Article 9 may be dissolved, wound up and liquidated at any time thereafter and, except in the case of a lease, such Person shall be released from its liabilities as obligor and maker of the Notes and from its obligations under this Supplemental Indenture.

In case of any such consolidation, merger, binding share exchange, sale, assignment, conveyance, transfer, lease or other disposition to another Person, such changes in phraseology and form (but not in substance) may be made in the Notes thereafter to be issued as may be appropriate.

Section 9.03 Officers’ Certificate and Opinion of Counsel to Be Given to Trustee. In the case of any such consolidation, merger, binding share exchange, sale, assignment, conveyance, transfer, lease or other disposition pursuant to Section 9.01, the Trustee shall receive an Officers’ Certificate and an Opinion of Counsel stating that any such consolidation, merger, binding share exchange, sale, assignment, conveyance, transfer, lease or other disposition and any such assumption and, if a supplemental indenture is required in connection with such transaction, such supplemental indenture, complies with the provisions of this Supplemental Indenture.

ARTICLE 10.
NO OPTIONAL REDEMPTION

Section 10.01 No Redemption Rights. The Company shall not redeem the Notes prior to Maturity, and no sinking fund is provided for the Notes. Neither Article XI nor Article XII of the Base Indenture shall apply to the Notes.

(a) The Trustee, prior to the occurrence of an Event of Default and after the curing of all Events of Default which may have occurred, undertakes to perform such duties and only such duties as are specifically set forth in this Supplemental Indenture and no implied covenants or obligations shall be read into this Supplemental Indenture against the Trustee. In case an Event of Default has occurred (which has not been cured or waived), the Trustee shall exercise such of the rights and powers vested in it by this Supplemental Indenture and use the same degree of care in its exercise as a prudent person would exercise under the circumstances in the conduct of his or her own affairs.

(b) Prior to the occurrence of an Event of Default and after the curing or waiving of all Events of Default which may have occurred:

(i) the duties and obligations of the Trustee shall be determined solely by the express provisions of this Supplemental Indenture and applicable law, and the Trustee shall not be liable except for the performance of such duties and obligations as are specifically set forth in this Supplemental Indenture and no implied covenants or obligations shall be read into this Supplemental Indenture against the Trustee; and

(ii) in the absence of bad faith on the part of the Trustee, the Trustee may conclusively rely as to the truth of the statements and the correctness of the opinions expressed therein, upon any certificates or opinions furnished to the Trustee and conforming to the requirements of this Supplemental Indenture; but, in the case of any such certificates or opinions which by any provisions hereof are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine the same to determine whether or not they conform to the requirements of this Supplemental Indenture (but need not confirm or investigate the accuracy of any mathematical calculations or other facts stated therein).

(c) No provision of this Supplemental Indenture shall be construed to relieve the Trustee from liability for its own negligent action, its own negligent failure to act or its own willful misconduct, except that:

(i) this subsection (c) does not limit the effect of this Section 11.01;

(ii) the Trustee shall not be liable for any error of judgment made in good faith, unless it is proved in a court of competent jurisdiction in a final and non-appealable decision that the Trustee was negligent in ascertaining the pertinent facts; and

(iii) the Trustee shall not be liable with respect to any action taken or omitted to be taken by it in good faith in accordance with the written direction of the Holders of not less than a majority in principal amount of the Notes at the time Outstanding determined as provided in Section 1.04 of the Base Indenture relating to the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee under this Supplemental Indenture;

(d) Whether or not therein provided, every provision of this Supplemental Indenture relating to the conduct or affecting the liability of, or affording protection to, the Trustee shall be subject to the provisions of this Section 11.01.

(e) The Trustee shall not be liable in respect of any payment (as to the correctness or calculation of amount, entitlement to receive or any other matters relating to payment) or notice effected by the Company or any Paying Agent or any records maintained by any co-Registrar with respect to the Notes.

(f) If any party fails to deliver a notice relating to an event the fact of which, pursuant to this Supplemental Indenture, requires notice to be sent to the Trustee, the Trustee may conclusively rely on its failure to receive such notice as reason to act as if no such event occurred.

(g) None of the provisions contained in this Supplemental Indenture shall require the Trustee to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties or in the exercise of any of its rights or powers if there is reasonable ground for believing that the repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it.

Section 11.02 Reserved

(f) The Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture or other paper or document, but the Trustee, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Company, personally or by agent or attorney (at the reasonable expense of the Company and shall incur no liability of any kind by reason of such inquiry or investigation).

(i) In no event shall the Trustee be responsible or liable for special, indirect, consequential or punitive loss or damage of any kind whatsoever (including, but not limited to, loss of profit) irrespective of whether the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action.

(k) The rights, privileges, protections, immunities and benefits given to the Trustee, including, without limitation, its right to be indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, and each Agent, custodian and other Person employed to act hereunder.

(l) The Trustee shall not be required to give any bond or surety in respect of the performance of its powers and duties hereunder.

(m) The Trustee may request that the Company deliver an Officers’ Certificate setting forth the names of individuals and/or titles of officers authorized at such time to take specified actions pursuant to this Supplemental Indenture.

Section 11.06 Monies to be Held in Trust. Subject to the provisions of Section 7.02, all monies and properties received by the Trustee shall, until used or applied as herein provided, be held in trust for the purposes for which they were received. Money held by the Trustee in trust hereunder need not be segregated from other funds except to the extent required by law. The Trustee shall be under no liability for interest on or the investment of any money received by it hereunder except as may be agreed in writing from time to time by the Company and the Trustee.

Section 11.07 Compensation and Expenses of Trustee. The Company covenants and agrees to pay to the Trustee from time to time, and the Trustee shall be entitled to, such compensation for all services rendered by it hereunder in any capacity (which shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust) as mutually agreed to from time to time in writing between the Company and the Trustee, and the Company shall pay or reimburse the Trustee upon its request for all reasonable expenses, disbursements and advances reasonably incurred or made by the Trustee in accordance with any of the provisions of this Supplemental Indenture (including the reasonable compensation and the expenses and disbursements of its counsel and of all Persons not regularly in its employ) except any such expense, disbursement or advance as may arise from its own negligence or willful

misconduct, as determined by a court of competent jurisdiction in a final non-appealable decision.

The Company also covenants to indemnify each of the Trustee and the Agents (and their respective officers, directors and employees), in any capacity under this Supplemental Indenture and their respective agents for, and to hold each of them harmless from and against, any and all loss, liability, claim, damage, cost or expense incurred without negligence or willful misconduct on its own part and arising out of or in connection with the acceptance or administration of this trust and the performance of its duties and/or the exercise of its rights hereunder or in any other capacity hereunder, including the costs and expenses of defending itself against any claim (whether asserted by the Company, a Holder or any other Person) of liability in the premises. The Trustee shall notify the Company promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Company shall not relieve the Company of its obligations hereunder, unless the Company is materially prejudiced thereby. The Company shall defend the claim and the Trustee shall cooperate in the defense. The Trustee may have separate counsel and the Company shall pay the reasonable fees and expenses of such counsel if (i) the Company shall have failed to assume the defense thereof or employed counsel reasonably satisfactory to the Trustee, or (ii) the Trustee has been advised by such counsel that there may be one or more defenses available to it that are different from or in addition to those available to the Company. The Company need not pay for any settlement made without its consent, which consent shall not be unreasonably withheld.

The obligations of the Company under this Section 11.07 to compensate or indemnify the Trustee and to pay or reimburse the Trustee for expenses, disbursements and advances shall be secured by a lien prior to that of the Notes upon all property and funds held or collected by the Trustee as such, except funds held in trust for the benefit of the Holders of particular Notes. The obligation of the Company under this Section 11.07 shall survive the payment of the Notes, the satisfaction and discharge of this Supplemental Indenture and/or the resignation or removal of the Trustee.

When the Trustee, any Agent, and any of their respective agents incur expenses or render services after an Event of Default specified in Section 6.01(i) or Section 6.01(j) with respect to the Company occurs, the expenses and the compensation for the services are intended to constitute expenses of administration under any bankruptcy, insolvency or similar laws.

Section 11.08 Officers’ Certificate as Evidence. Subject to Section 11.01, whenever in the administration of the provisions of this Supplemental Indenture the Trustee shall deem it necessary or desirable that a matter be proved or established prior to taking or omitting any action hereunder, such matter (unless other evidence in respect thereof be herein specifically prescribed) may, in the absence of bad faith on the part of the Trustee, be deemed to be conclusively proved and established by an Officers’ Certificate delivered to the Trustee.

Section 11.09 Conflicting Interests of Trustee. If the Trustee has or shall acquire a conflicting interest within the meaning of the Trust Indenture Act, the Trustee shall either eliminate such interest or resign, to the extent and in the manner provided by, and subject to the provisions of, this Supplemental Indenture.

Section 11.10 Eligibility of Trustee. There shall at all times be a Trustee hereunder which shall be a Person that is eligible pursuant to the Trust Indenture Act to act as such and has a combined capital and surplus of at least $50,000,000 (or if such Person is a member of a bank holding company system, its bank holding company shall have a combined capital and surplus of at least $50,000,000). If such Person publishes reports of condition at least annually, pursuant to law or to the requirements of any supervising or examining authority, then for the purposes of this Section the combined capital and surplus of such Person shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time the Trustee shall cease to be eligible in accordance with the provisions of this Section 11.10, it shall resign immediately in the manner and with the effect hereinafter specified in this Article.

Section 11.11 Resignation or Removal of Trustee.

(a) The Trustee may at any time resign by giving written notice of such resignation to the Company and to the Holders of Notes. Upon receiving such notice of resignation, the Company shall promptly appoint a successor trustee by written instrument, in duplicate, executed by order of the Board of Directors, one copy of which instrument shall be delivered to the resigning Trustee and one copy to the successor trustee. If no successor trustee shall have been so appointed and have accepted appointment thirty (30) days after such notice of resignation is given to the Company and the Holders, the resigning Trustee may, upon ten (10) Business Days’ notice to the Company and the Holders, appoint a successor identified in such notice or may petition, at the expense of the Company, any court of competent jurisdiction for the appointment of a successor trustee, or, if any Holder who has been a bona fide Holder of a Note or Notes for at least six (6) months may, subject to the provisions of Section 6.15, on behalf of himself and all others similarly situated, petition any such court for the appointment of a successor trustee. Such court may thereupon, after such notice, if any, as it may deem proper and prescribe, appoint a successor trustee.

(b) In case at any time any of the following shall occur:

(i) the Trustee shall fail to comply with Section 11.09 after written request therefor by the Company or by any Holder who has been a bona fide Holder of a Note or Notes for at least six (6) months; or

(ii) the Trustee shall cease to be eligible in accordance with the provisions of Section 11.10 and shall fail to resign after written request therefor by the Company or by any such Holder; or

(iii) the Trustee shall become incapable of acting, or shall be adjudged a bankrupt or insolvent, or a receiver of the Trustee or of its property shall be appointed, or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation;

then, in any such case, the Company may remove the Trustee and appoint a successor trustee by written instrument, in duplicate, executed by order of the Board of Directors, one copy of which instrument shall be delivered to the Trustee so removed and one copy to the successor trustee, or, subject to the provisions of Section 6.15, any Holder who has been a bona fide Holder of a Note or Notes for at least six (6) months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor trustee; provided, however, that if no successor Trustee shall have been appointed and have accepted appointment thirty (30) days after either the Company or the Holders has removed the Trustee, the Trustee so removed may petition at the Company’s expense any court of competent jurisdiction for an appointment of a successor trustee. Such court may thereupon, after such notice, if any, as it may deem proper and prescribe, remove the Trustee and appoint a successor trustee.

(c) The Holders of a majority in aggregate principal amount of the Notes at the time Outstanding may at any time remove the Trustee and nominate a successor trustee which shall be deemed appointed as successor trustee unless, within ten (10) days after notice to the Company of such nomination, the Company objects thereto, in which case the Trustee so removed or any Holder, or if such Trustee so removed or any Holder fails to act, the Company, upon the terms and conditions and otherwise as in Section 11.11(a) provided, may petition any court of competent jurisdiction for an appointment of a successor trustee.

(d) Any resignation or removal of the Trustee and appointment of a successor trustee pursuant to any of the provisions of this Section 11.11 shall become effective upon acceptance of appointment by the successor trustee as provided in Section 11.12.

Section 11.12 Acceptance by Successor Trustee. Any successor trustee appointed as provided in Section 11.11 shall execute, acknowledge and deliver to the Company and to its predecessor trustee an instrument accepting such appointment hereunder, and thereupon the resignation or removal of the predecessor trustee shall become effective and such successor trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, duties and obligations of its predecessor hereunder, with like effect as if originally named as trustee herein; but, nevertheless, on the written request of the Company or of the successor trustee, the trustee ceasing to act shall, upon payment of any amount then due it pursuant to the provisions of Section 11.07, execute and deliver an instrument transferring to such successor trustee all the rights and powers of the trustee so ceasing to act. Upon request of any such successor trustee, the Company shall execute any and all instruments in writing for more fully and certainly vesting in and confirming to such successor trustee all such rights and powers. Any trustee ceasing to act shall, nevertheless, retain a lien upon all property and funds held or collected by such trustee as such, except for funds held in trust for the benefit of Holders of particular Notes, to secure any amounts then due it pursuant to the provisions of Section 11.07.

No successor trustee shall accept appointment as provided in this Section 11.12 unless, at the time of such acceptance, such successor trustee shall be qualified under the provisions of Section 11.09 and be eligible under the provisions of Section 11.10.

Upon acceptance of appointment by a successor trustee as provided in this Section 11.12, the Company (or the former trustee, at the written direction of the Company) shall give or cause to be given notice of the succession of such trustee hereunder to the Holders of Notes in accordance with Section 12.08(c). If the Company fails to give such notice within ten (10) days after acceptance of appointment by the successor trustee, the successor trustee shall cause such notice to be given at the expense of the Company.

Section 11.13 Succession by Merger, Etc. Any corporation into which the Trustee may be merged or exchanged or with which it may be consolidated, or any corporation resulting from any merger, exchange or consolidation to which the Trustee shall be a party, or any corporation succeeding to all or substantially all of the corporate trust business of the Trustee (including any trust created by this Supplemental Indenture), shall be the successor to the Trustee hereunder without the execution or filing of any paper or any further act on the part of any of the parties hereto, provided that in the case of any corporation succeeding to all or substantially all of the corporate trust business of the Trustee, such corporation shall be qualified under the provisions of Section 11.09 and eligible under the provisions of Section 11.10.

In case at the time such successor to the Trustee shall succeed to the trusts created by this Supplemental Indenture, any of the Notes shall have been authenticated but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any predecessor trustee or authenticating agent appointed by such predecessor trustee, and deliver such Notes so authenticated; and in case at that time any of the Notes shall not have been authenticated, any successor to the Trustee or any authenticating agent appointed by such successor trustee may authenticate such Notes in the name of the successor trustee; and in all such cases such certificates shall have the full force that is provided in the Notes or in this Supplemental Indenture; provided, however, that the right to adopt the certificate of authentication of any predecessor Trustee or authenticate Notes in the name of any predecessor Trustee shall apply only to its successor or successors by merger, exchange or consolidation.

Section 11.14 Preferential Collection of Claims. If and when the Trustee shall be or become a creditor of the Company (or any other obligor upon the Notes), the Trustee shall be subject to the provisions of the Trust Indenture Act regarding the collection of the claims against the Company (or any such other obligor).

Section 11.15 Trustee’s Application for Instructions from the Company. Any application by the Trustee for written instructions from the Company (other than with regard to any action proposed to be taken or omitted to be taken by the Trustee that affects the rights of the Holders of the Notes under this Supplemental Indenture) may, at the option of the Trustee, set forth in writing any action proposed to be taken or omitted by the Trustee under this Supplemental Indenture and the date on and/or after which such action shall be taken or such omission shall be effective. The Trustee shall not be liable for any action taken by, or omission of, the Trustee in accordance with a proposal included in such application on or after the date specified in such

application (which date shall not be less than three (3) Business Days after the date any officer of the Company actually receives such application, unless any such officer shall have consented in writing to any earlier date) unless prior to taking any such action (or the effective date in the case of an omission), the Trustee shall have received written instructions in response to such application specifying the action to be taken or omitted.

Section 12.08 Notices.

(a) Except as otherwise provided herein, any request, demand, authorization, direction, notice, consent, election, waiver or Act of Holders or other document provided or permitted by this Supplemental Indenture to be made upon, given or furnished to, or filed with, the Company or the Trustee shall be in writing and delivered in person or mailed by first class mail, postage prepaid, overnight courier or transmitted by facsimile transmission or electronic transmission in PDF format as follows:

Each other party agrees to assume all risks arising out of the use of electronic methods to submit instructions, directions, reports, notices or other communications or information to the Trustee, including, without limitation the risk of the Trustee acting on unauthorized instructions, notices, reports or other communications or information, and the risk of interception and misuse by third parties.

Each Holder, by accepting a Note, waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes.

Section 12.10 Tax Withholding. Nothing herein shall preclude any tax withholding required by law or regulation. In particular, any deemed distribution treated as a dividend generally would not give rise to any cash from which any applicable withholding tax could be satisfied and, therefore, if withholding taxes, including backup withholding, are paid on behalf of a Holder or beneficial owner, those withholding taxes may be set off against payments of cash or common stock, if any, payable on the Notes or, in some circumstances, against any payments on the Common Stock.

The parties to this Supplemental Indenture agree that they

shall provide the Trustee with such information as it may request in order for the Trustee to satisfy the requirements of the U.S.A. Patriot Act.

This Note does not benefit from a sinking fund. This Note is not subject to redemption at the option of the Company.

As provided in and subject to the provisions of the Indenture, upon the occurrence of a Fundamental Change, the Holder of this Note shall have the right, at such Holder’s option, to require the Company to purchase this Note, or any portion of this Note (in principal amounts of $1,000 or an integral multiple of $1,000 in excess thereof), on the Fundamental Change Purchase Date at a price equal to the Fundamental Change Purchase Price for such Fundamental Change Purchase Date.

As provided in and subject to the provisions of the Indenture, the Holder hereof has the right, at any time until the Close of Business on the second Scheduled Trading Day immediately preceding the Maturity Date, to convert this Note or a portion of this Note such that the principal amount of this Note converted equals $1,000 or an integral multiple of $1,000 in excess thereof, into a number of shares of Common Stock and an amount in cash, if any, in lieu of fractional shares, determined in accordance with Article 4 of the Supplemental Indenture and subject to adjustment as set forth therein.
